I'm encountering an error and reviewing the docs at /flg~eyJhbGciOiJIUzI1NiJ9._v7-_v79_g.IN_1YP9lSd3iAlrWfWlSjd7w2BXkRLu_kcJ1imlrEiA/docs/errors/INVALID_IMAGE_OPTIMIZE_REQUEST to understand what's happening. Please help me resolve this by: 1. **Suggest the fix**: Analyze my codebase context and propose what needs to be changed to resolve this error 2. **Explain the root cause**: Break down why this error occurred: - What was the code actually doing vs. what it needed to do? - What conditions triggered this specific error? - What misconception or oversight led to this? 3. **Teach the concept**: Help me understand the underlying principle: - Why does this error exist and what is it protecting me from? - What's the correct mental model for this concept? - How does this fit into the broader framework/language design? 4. **Show warning signs**: Help me recognize this pattern in the future: - What should I look out for that might cause this again? - Are there similar mistakes I might make in related scenarios? - What code smells or patterns indicate this issue? 5. **Discuss alternatives**: Explain if there are different valid approaches and their trade-offs My goal is to fix the immediate issue while building lasting understanding so I can avoid and resolve similar errors independently in the future.

To troubleshoot this error, follow these steps:

  1. Check for typos: Verify that there are no typos in the parameter names or values

    • The parameter controls the quality of the image and must follow these rules:
      • The parameter must be an integer
      • The integer must be greater than or equal to 1
      • The integer must be less than or equal to 100
      • The integer must be the same as one specified in , if defined
    • The parameter defines the width of the image and must follow these rules:
