Bug type
Behavior bug (incorrect output/state without crash)
Summary
Every call to edit tool fails with the error message "[tools] edit failed: Missing required parameters: oldText (oldText or old_string), newText (newText or new_string). Supply correct parameters before retrying.", forcing the model to use write tool to complete the file update operation.
Steps to reproduce
Waiting for the Heartbeat to be triggered or manually triggering the Heartbeat, if this Heartbeat requires file updates, the issue will arise.
Expected behavior
Edit tool should work normally.
Actual behavior
Console outputs "[tools] edit failed: Missing required parameters: oldText (oldText or old_string), newText (newText or new_string). Supply correct parameters before retrying.", and sometimes the same error repeats up to more than ten times ( LLMs repeatedly attempts to use edit ).
By examining the jsonl, it was found that after several failed attempts to use edit, the LLMs would directly use write tool to update the file content, which is actually a quite dangerous operation and can easily lead to the loss of a large amount of data. Fortunately, as of now, no data has been lost.
By reviewing the jsonl, it was also found that when calling edit tool, most of the time the LLMs does not return both the oldText and newText parameters, only the file_path and path parameters. In a few cases, the large model only returns oldText and not newText.
