when i push the image to the tira server, it keep showing the following message:docker.errors.APIError: 500 Server Error for http+docker Internal Server Error (“invalid reference format”).The deadline for software submission is approaching！！！ 
Is there a problem with the tira server?
Dear @ZhijianHuang,
Thanks for reaching out!
We will resolve this. (The software submission deadlines are soft, i.e., it is no problem to have individual extensions.) There is no problem with the tira server at the moment, but the tira-run command inspects the docker image before uploading it to TIRA to also upload some meta data. The problem can be that the executable specified in the --command flag is not available in the docker image or can not be found.
I will reach out to you in a personal message to resolve the problem.
Best regards,
Maik
