Hello @kindy! I'm here to help you with any bugs, questions, or contributions you have for the Dify project. Let's work together to resolve the issue you're facing.

The error you're encountering with the i18n/check-i18n.js script is likely due to the script attempting to evaluate a file content that does not result in a valid object. Specifically, it seems that one of the translation files, such as web/i18n/en-US/register.ts, might be exporting an empty object or is missing the expected keys and values [1].

To resolve this issue, you should:

  1. Check the Translation Files: Ensure that all translation files in the en-US directory, including register.ts, are populated with the necessary keys and values. These files should contain key-value pairs where the key is a string identifier used in the application, and the value is the English translation of that string [2].

  2. Add Error Handling: Consider adding error handling around the eval statement in the script to catch and log any issues with specific files. This can help identify which files are causing the problem.

By ensuring that the translation files are correctly populated and adding error handling, you should be able to run the script without encountering the "TypeError: Cannot convert undefined or null to object" error.

To continue talking to Dosu, mention @dosu.
