Search and Replace Identical Error #2188
Description
App Version
3.11.3
API Provider
Google Gemini
Model Used
Gemini 2.5 Pro exp 3-25
Actual vs. Expected Behavior
Actual Behavior:
Error
<error_details>
Search and replace content are identical - no changes would be made
Debug Info:
- Search and replace must be different to make changes
- Use read_file to verify the content you want to change
</error_details>
Roo is having trouble...
Roo Code uses complex prompts and iterative task execution that may be challenging for less capable models. For best results, it's recommended to use Claude 3.7 Sonnet for its advanced agentic coding capabilities.
Expected Behavior:
We noticed the suggested content and existing content are identical. Moving On...
Detailed Steps to Reproduce
- Prompt: Work to resolve failing jest tests
Relevant API Request Output
<error_details>
No sufficiently similar match found at start: 87 to end: 87 (72% similar, needs 100%)
Debug Info:
- Similarity Score: 72%
- Required Threshold: 100%
- Search Range: lines 87-87
- Tip: Use read_file to get the latest content of the file before attempting the diff again, as the file content may have changed
