TL;DR

The issue is likely due to exceeding the maximum allowed size or tokens for file content, and using offset and limit parameters to read specific portions of the file may resolve the issue.

Guidance

• Review the error messages to identify specific issues, such as "Request exceeds the maximum size" or "File content exceeds maximum allowed tokens".
• Consider using offset and limit parameters to read specific portions of the file instead of reading the whole file.
• Check the Usage Policy (https://www.anthropic.com/legal/aup) to ensure compliance with the API usage guidelines.
• Verify that the file size is within the allowed limits (e.g., 256KB) and adjust accordingly.

Example

No specific code snippet can be provided without more context, but using offset and limit parameters might look like: readFile({ offset: 0, limit: 10000 }).

Notes

The issue may be related to changes in the API usage policy or file size limits, and it's essential to review the policy and adjust the code accordingly. The provided error messages indicate a variety of issues, including file size and token limits, and it's crucial to address each error separately.

Recommendation

Apply a workaround by using offset and limit parameters to read specific portions of the file, and review the Usage Policy to ensure compliance with the API usage guidelines. This approach should help resolve the issue without requiring an upgrade to a fixed version.
