添加法语版本时项目预览失败：projectId参数报错咨询

Hey there, let's work through this error you're hitting while uploading the French Excel localization for your mr-html project. I've tackled similar trivia template localization hiccups before, so here are the key checks to run:

• Verify project ID consistency
  Make sure the project ID you're using during upload is an exact match for your approved project: mr-html. Typos, extra spaces, or incorrect capitalization (like Mr-HTML instead of mr-html) will trigger this parameter error. Cross-check it against the ID shown in your project dashboard and the one you used when adding French in Project Actions.

• Validate the French Excel file structure
  Trivia templates have strict formatting rules for localized files. Confirm:

  • The sheet name matches the exact convention from your approved English file (don't rename it unless the template docs specify otherwise)
  • All mandatory columns (question text, answers, hints, etc.) are present and aligned with the English version
  • The French locale code is correctly set (usually fr or fr-FR, depending on the platform's requirements)
  • There are no merged cells, broken formulas, or unescaped special characters that could break parsing

• Double-check the language setup in Project Actions
  After adding French in Actions, ensure the language is fully activated and linked to mr-html. Sometimes the addition doesn't save properly—try refreshing the dashboard, removing and re-adding the French locale, and confirming it's marked as a supported language for the project before uploading the file.

• Test with a simplified Excel file
  To rule out file-specific issues, create a stripped-down French file with just 1-2 test questions (mirroring your approved English file's structure) and try uploading that. If this works, the problem is likely in the full file—look for corrupted rows, invalid data in a specific cell, or formatting quirks that are breaking the preview.

• Clear session/cache glitches
  Temporary session mismatches can cause this error too. Try logging out and back into the platform, clearing your browser cache, or using an incognito window to attempt the upload again. This can resolve any cached inconsistencies between your project ID and the upload request.

If none of these steps fix the issue, reach out to the platform's support team with:

• A screenshot of the error message
• A redacted copy of your French Excel file
• The exact steps you took to add the language and upload the file
  They’ll be able to dig into the parameter validation logs for your mr-html project.
