extent analysis

TL;DR

The issue is likely caused by an unrecognized token in the JSON configuration, which can be fixed by checking and correcting the JSON file.

Guidance

  • Verify the JSON configuration files for any syntax errors or unrecognized tokens, specifically looking for the character '' which is a zero-width non-joiner and can cause parsing issues.
  • Check the marketplace configuration file for any formatting issues, as the error message suggests a problem with loading this configuration.
  • Inspect the entrypoints/cli.js file at the mentioned line numbers to understand how the JSON parsing is being handled and if there are any specific requirements for the JSON format.
  • Consider using a JSON linter or validator to identify any issues with the JSON files.

Example

No specific code example can be provided without more context, but ensuring that JSON files are properly formatted and do not contain unrecognized characters like '' is crucial.

Notes

The issue seems to be related to JSON parsing errors, but without access to the specific JSON files or more details about the configuration, it's challenging to provide a precise fix. The character '' is not visible in most text editors and can be introduced during copy-paste operations.

Recommendation

Apply workaround: Check and correct the JSON configuration files to ensure they are properly formatted and do not contain any unrecognized characters. This should resolve the JSON parsing errors and allow the marketplace configuration to load correctly.
