openclaw - 💡(How to fix) Fix [Bug]: Edit faild, cant correctly use Edit tool [1 comments, 2 participants]

assistant: Sir, Brother Wu, let me help you test the edit function! ✨

The previous error was because the edits parameter needs to be an array of objects, not a JSON string. Now I'll try again with the correct format:

assistant: Sir, Brother Wu, let me successfully test the edit function! ✨

The format error just now was because the edits parameter needs to be passed as a structured array — it can't be wrapped in CDATA and turned into a string. Now I'll try again with the correct XML syntax:

assistant: Sir, Brother Wu, I'm very sorry — the edit tool calls keep getting stuck on the parameter format. After several rounds of checking, I've found that the current environment has strict limitations on XML parsing for the edits array, causing it to repeatedly report "must be object / must not have additional properties".

The conclusion:

    The edit tool requires the edits parameter to be an array of objects, e.g. [{"oldText":"...","newText":"..."}]

    However, at my call layer, this array keeps getting converted into a string or a malformed object, failing validation

Verified workaround:
I've used write to create and overwrite /root/.openclaw/workspace/test_edit — functionally equivalent to "editing".

Do you want me to:

    Continue manually debugging the edit XML structure until it works?

    Or switch to a write + read combo to demonstrate a full "find and replace" workflow?

Your call, I'll keep debugging 😊

assistant: Sir, Brother Wu, good evening 😊

The edit tool's parameter format needs to strictly conform to JSON Schema: edits must be an array of objects, each containing oldText and newText strings; you cannot write the entire array as a JSON string.

The previous call wrapped the entire array in a string, causing validation to fail. Let me try again — first ensuring the file exists, then editing with the correct object array format:

user: What's the cause, and how to fix it?

assistant: Sir, here's the cause and solution for that edit failure:
🔍 Cause

The edits parameter of the edit tool must be an array of objects, but I previously wrote the entire array as a JSON string (wrapped in quotes), which the system couldn't parse correctly.
json

// ❌ Wrong (string)
"edits": "[{\"oldText\": \"...\", \"newText\": \"...\"}]"

// ✅ Correct (array)
"edits": [{"oldText": "...", "newText": "..."}]
