Dear @prisha2410,
Thanks for reaching out!
We will likely extend the deadline.
The 500 error is likely this problem that the image is not compatible with the docker registry.
This is due to a recent update in Docker desktop, the link above describes the steps to resolve the problem. Could you update your tira client ( pip3 install --upgrade tira ) for this and run the steps in the link above?
And could you please also use the tira-cli code-submission, as this should (after the update) automatically detect the problem?
Best regards,
Maik
