Summary

This PR improves error messaging in the Plugin service by adding more detailed context to the error message when no options are returned. The change enhances debugging capabilities by including the specific parameter and provider information in the error message, making it easier for developers to identify and troubleshoot issues.

Changes made:

  • Modified the error message in api/core/plugin/impl/dynamic_select.py to include parameter and provider details
  • Changed from generic "Plugin service returned no options" to more descriptive "Plugin service returned no options for parameter '{parameter}' in provider '{provider}'"

This is a minor enhancement that improves the developer experience when working with plugin dynamic select functionality.

Screenshots

Before After
