feishu_doc(action="write", doc_token="Mbv0drINRoC67qxqjxPctBMknqF", content="Test content")

PR fix notes

PR #61367: fix(feishu_doc): guard against undefined content in write/append/insert actions

Description (problem / solution / changelog)

Summary

Fixes #61336 - feishu_doc action=write crashes with Cannot read properties of undefined (reading 'split') when content parameter is not passed.

Root Cause

writeDoc, appendDoc, and insertDoc all call chunkedConvertMarkdown which calls markdown.split('\n') without checking if markdown is undefined/null first.

Fix

  • writeDoc: Returns early with zero counts when content is empty (avoids clearing document unnecessarily)
  • appendDoc: Throws 'Content is required' error before making API calls
  • insertDoc: Throws 'Content is required' error before making API calls

Repro (from issue)

feishu_doc action=write, content=undefined  # crashes

Steps to Reproduce

# Returns: document_id: Mbv0drINRoC67qxqjxPctBMknqF

  2. Write to document (failure):

    feishu_doc(action="write", doc_token="Mbv0drINRoC67qxqjxPctBMknqF", content="Test content")
# Error: Cannot read properties of undefined (reading 'split')

Expected Behavior

Document content should be written successfully.

extent analysis

TL;DR

The feishu_doc tool's write action fails due to an undefined property error, suggesting a potential issue with the content parameter or the underlying implementation.

Guidance

  • Verify that the content parameter is correctly formatted and does not contain any unexpected characters or structures that could cause the split method to fail.
  • Check the implementation of the feishu_doc tool to ensure that it properly handles the content parameter and any potential edge cases.
  • Consider using the suggested workaround of using Feishu Bitable for structured data storage, as it is reported to be working.
  • Investigate the difference in implementation between the Document Write and Bitable Write features, as the latter is reported to be working.

Example

No code snippet can be provided without more information about the implementation of the feishu_doc tool.

Notes

The exact cause of the error is unclear without more information about the implementation of the feishu_doc tool. The suggested workaround may not be suitable for all use cases, especially if the content is not structured data.

Recommendation

Apply workaround: Using Feishu Bitable for structured data storage may be a viable temporary solution until the issue with the feishu_doc tool is resolved.
