• Error: fields parameter fails with "Expected object, received string" — the tool cannot be used at all as a result

Error Messages/Logs

Error: MCP error -32602: Input validation error: Invalid arguments for tool editJiraIssue: [

TL;DR

The fields parameter in the editJiraIssue tool should be passed as an object instead of a string to resolve the "Expected object, received string" error.

Guidance

• Verify that the fields parameter is being passed correctly as an object, with the required properties, to the editJiraIssue tool.
• Check the documentation for the editJiraIssue tool to ensure that the fields parameter is being used as intended.
• Review the code that calls the editJiraIssue tool to ensure that the fields object is being constructed and passed correctly.
• If the issue persists, try logging the fields object before passing it to the editJiraIssue tool to verify its structure and contents.

Example

No code example can be provided without more context, but the fields object should be constructed in a format similar to { key: value }, where key is the field name and value is the field value.

Notes

The error message indicates that the fields parameter is being passed as undefined, which may indicate a separate issue with how the fields object is being constructed or passed.

Recommendation

Apply workaround: Pass the fields parameter as an object with the required properties to the editJiraIssue tool, as this is the most likely cause of the error.
