Dify version

1.7.2

Plugin version

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

Describe

Some tools, such as the JSON, Regex, and DateTime tools, still output exception content when an error occurs, instead of triggering the designated exception handling branch. This prevents proper error handling and flow control within the application.

Expected behavior

When an exception occurs (e.g., due to invalid input for JSON, Regex, or DateTime tools), the tool should trigger the designated exception handling branch. It should not return the error message as a normal result.

✔️ Error log

Hi, @fairyto2. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You reported that in Dify version 1.7.2 (self-hosted), tools like JSON, Regex, and DateTime output exception details directly on errors.
  • This behavior bypasses the proper exception handling branch, causing exceptions to be returned as normal results.
  • This disrupts error handling and flow control as intended.
  • No further updates or comments have been provided since your initial report.

Next Steps:

  • Please let me know if this issue is still relevant with the latest version of dify-official-plugins by commenting below.
  • If I do not hear back within 5 days, I will automatically close this issue.

Thank you for your understanding and contribution!
