[{"error":"Error: File does not exist.

TL;DR

The issue is likely due to a JSON parsing error caused by an unexpected end of input, possibly resulting from a rate limit error or a non-existent file.

Guidance

• Check the request being made to ensure it is not exceeding the account's rate limit, as indicated by the "rate_limit_error" message in the error log.
• Verify that the file being referenced in the error message exists in the specified directory (/Users/chill/Desktop/SaaS).
• Review the code to ensure proper error handling for JSON parsing, considering the potential for incomplete or malformed JSON responses.
• Inspect the call function in cli.js to understand how it handles file existence checks and JSON execution.

Example

No code example is provided due to the lack of specific code context in the issue.

Notes

The provided error messages suggest two distinct issues: a file not found error and a rate limit error. The JSON parsing error might be a consequence of one of these issues. Without more context or code, it's challenging to provide a definitive solution.

Recommendation

Apply workaround: Implement rate limiting handling and file existence checks in your code to mitigate these errors, as upgrading to a fixed version is not explicitly implied in the provided information.
