Common Causes of the “expected Value At Line 1 Column 1 Path $” Error

The error message `expected Value At Line 1 Column 1 Path $` typically indicates a problem with parsing JSON data in Shadowrocket or similar applications. This error arises when the JSON parser expects a valid JSON value at the beginning of the input but encounters invalid syntax or unexpected characters instead. Understanding the common causes can help diagnose and resolve the issue more efficiently.

One primary cause is an empty or malformed response from the server or source providing the JSON configuration or subscription data. For example, if the server returns an empty string, an HTML error page, or any non-JSON response, the parser cannot interpret it as valid JSON, resulting in this error.

Another frequent cause is incorrectly formatted subscription URLs or configuration files. If the URL points to a non-JSON resource or includes additional characters (such as BOM markers or whitespace before the JSON), the parser may fail immediately at the first character.

Network issues, such as incomplete downloads or interrupted connections, can also lead to partial JSON content being parsed, triggering this error. In some cases, proxy settings or firewall restrictions might modify or block the response, causing the JSON parser to fail.

Finally, outdated or incompatible app versions might misinterpret valid JSON responses if there are changes in expected formats or encryption. Ensuring the app is updated can sometimes resolve parsing errors.

Troubleshooting Steps to Resolve the Error

To effectively address the `expected Value At Line 1 Column 1 Path $` error, follow these steps:

Verify the JSON Source: Check the URL or file providing the JSON data. Ensure it returns a valid JSON string by opening it in a web browser or using tools like `curl` or Postman.

Inspect Response Content: If the source returns HTML or error messages instead of JSON, the issue lies with the server or network. Confirm the subscription URL is correct and the server is operational.

Check Network Connectivity: Ensure stable internet connections and that proxies or firewalls do not interfere with the data transmission.

Validate JSON Format: Use JSON validators to confirm the structure is correct and free of syntax errors.

Update Shadowrocket: Install the latest version of the app to ensure compatibility with current JSON subscription formats.

Clear Cache and Reload: Sometimes cached data may cause parsing errors. Clearing the app cache and reloading the subscription can fix this.

Test with Alternative Sources: Try loading a different known-good subscription to determine whether the problem is specific to one URL or general.

Example JSON Validation Checklist

Below is a checklist to systematically validate JSON sources to prevent the error:

Check	Description	Tools/Methods
Valid JSON Syntax	Confirm the JSON string is properly formatted with correct braces, commas, and quotation marks.	JSONLint, Online JSON Validators
Correct Content Type	Ensure server response header includes ‘Content-Type: application/json’.	Browser Dev Tools, curl -I command
Non-empty Response	Check that the response body is not empty or an error page.	curl, Postman, Direct URL Access
No Leading Characters	Verify there are no BOM markers or whitespace before the JSON begins.	Text editors with hex view, Notepad++, Sublime Text
Network Stability	Confirm no interruptions or proxy modifications during download.	Network monitors, Ping tests
App Compatibility	Use the latest Shadowrocket version to avoid parsing incompatibilities.	App Store updates, Developer release notes

Advanced Debugging Techniques

For users with technical expertise, further steps can assist in pinpointing the exact cause of the JSON parsing error:

Capture Raw HTTP Traffic: Use tools like Charles Proxy or Wireshark to intercept and analyze the raw response from the subscription server. Look for anomalies in the HTTP status code, headers, or content.

Manually Download and Parse JSON: Save the JSON response to a local file and attempt to parse it with command-line tools such as `jq`. This helps isolate whether the issue is in the app or the source.

Enable App Debug Logs: If Shadowrocket or related apps support verbose logging, enable it to get detailed error messages about JSON parsing failures.

Check Encoding Settings: Ensure the JSON data is UTF-8 encoded without BOM, as improper encoding can cause parsing errors.

Review Subscription Format Updates: Some providers update their subscription formats. Consult provider documentation or forums to confirm compatibility.

By systematically applying these methods, users can identify and correct the root cause of the `expected Value At Line 1 Column 1 Path $` error, restoring proper functionality to Shadowrocket configurations.

Understanding the “Expected Value At Line 1 Column 1 Path $” Error in Shadowrocket

The error message “expected Value at line 1 column 1 path $” typically indicates a problem with the JSON or configuration file format that Shadowrocket is attempting to parse. This error suggests that the parser encountered an unexpected token or empty input at the very beginning of the file, which prevents proper loading and interpretation of the configuration.

Shadowrocket relies heavily on correctly structured JSON or plist files for proxy configurations, rules, and other settings. Any deviation from expected syntax will lead to parsing failures.

Common Causes of the Error

Empty or Corrupted Configuration File: The file being loaded is either empty or contains invalid data.
Incorrect File Encoding: The configuration file may not be saved in UTF-8 encoding, leading to invalid character interpretation.
Malformed JSON Syntax: Missing braces, brackets, commas, or quotes in the JSON structure.
Unexpected Characters or BOM (Byte Order Mark): Hidden characters at the start of the file can confuse the parser.
Incorrect File Format: Loading a non-JSON file or a configuration exported from an incompatible app/version.

Steps to Diagnose and Resolve the Issue

Step	Action	Expected Outcome
1	Open the configuration file with a plain text editor (e.g., VS Code, Sublime Text)	Verify the file is not empty and contains valid JSON content
2	Check file encoding and convert to UTF-8 if necessary	Ensure the file does not contain hidden invalid characters
3	Validate JSON syntax using online JSON validators or tools	Identify and fix missing commas, brackets, or quotes
4	Remove any Byte Order Mark (BOM) or invisible characters at the start	Parser correctly interprets the first character of the JSON
5	Ensure the file matches the expected Shadowrocket configuration format	Prevents incompatibility issues

Best Practices for Creating Shadowrocket Configurations

Always use a reputable text editor that supports syntax highlighting for JSON.
Avoid manual editing of configuration files unless familiar with JSON syntax.
Export configurations from trusted sources or official Shadowrocket-compatible exporters.
Regularly validate configuration files after making edits.
Backup working configurations before making changes to prevent data loss.

Example of a Valid Minimal Shadowrocket Configuration JSON

{
  "configs": [
    {
      "type": "ss",
      "tag": "Example Proxy",
      "server": "1.2.3.4",
      "port": 8388,
      "method": "aes-256-gcm",
      "password": "password123"
    }
  ],
  "index": 0,
  "global": ,
  "enabled": true,
  "shareOverLan": ,
  "bypass": [
    "127.0.0.1/8",
    "localhost"
  ],
  "proxy": {
    "all": "Example Proxy",
    "bypass": "DIRECT"
  }
}

This example highlights the proper JSON structure expected by Shadowrocket, starting immediately with an object containing a `configs` array. Any deviation such as missing braces or empty files can trigger the error.

Additional Diagnostic Tools and Resources

JSONLint: An online JSON validator to quickly check syntax correctness.
Shadowrocket GitHub repositories or forums: Community discussions may highlight common pitfalls.
Shadowrocket official documentation: Guidelines on supported configuration formats and versions.
Hex editors: Useful for detecting and removing invisible or non-printable characters.

By following these guidelines and carefully verifying configuration files, users can avoid the “expected Value at line 1 column 1 path $” error and ensure smooth operation of Shadowrocket.
