Internal Server Error when submitting to leaderboard version 3

[OKR9871]

Hi, thank you for maintaining this great repository.

I am trying to submit results to the leaderboard version 3, but the submission fails with an Internal Server Error.

I followed the instructions in the README:

1. Downloaded the kin-zhang/multidata-sf-challenge dataset from Hugging Face.
2. Ran evaluation on the test split with leaderboard_version=3.
3. Generated the submission zip file successfully.
4. Tried to upload the zip file to the leaderboard server.

However, the server returns:

Internal Server Error

Could you please check whether the leaderboard v3 submission server is currently working correctly, or whether there is any additional requirement for the submission zip format?

Please let me know if you need the exact error log, zip structure, or any additional information.

Thank you!

Ishan, bring it back; try it now, and see if you got the leaderboard result.

Thank you for the quick fix. I tried the submission again, and it works now.
