TL;DR

The issue is likely caused by an invalid string length error in the Mu.write function, and a potential workaround is to check the input data being written to ensure it is valid.

Guidance

  • Verify that the input data being passed to the Mu.write function is not exceeding the maximum allowed string length.
  • Check the documentation for the Mu.write function to see if there are any specific requirements or limitations for the input data.
  • Test the application with a smaller input dataset to see if the error persists, which could help isolate the issue.
  • Consider reaching out to the Codex App support team for further assistance, as the issue may be related to a specific version or configuration of the application.

Notes

The provided information does not include the specific code or data that is causing the error, so it is difficult to provide a more detailed solution. Additionally, the issue may be specific to the Version 26.422.30944 (2080) of the Codex App.

Recommendation

Apply workaround: The error message suggests an invalid string length, so checking and validating the input data being written is a reasonable first step to try and resolve the issue.
