Hi all, I'm new to docker. I just submitted one submission to challenge 2 express lane. After I got the first email: We have received your submission to the MM_Challenge_2_Express_Lane and confirmed that it is correctly formatted. and second email: Your submission "syn10569759" (ID: 9632305) to the MM_Challenge_2_Express_Lane has run successfully: the third email said, Sorry, but we were unable to validate your submission to the MM_Challenge_2_Express_Lane. There is the error msg in log file: 500 Server Error: Internal Server Error for url: http+docker://localunixsocket/v1.24/containers/96e2b35c8990aa17161b3d2e8d89748a3759ab61aba63c0bcb5bb8687d504152/start ("invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"exec: \\\"/score_sc2.sh\\\": permission denied\"\n"") Provenance Could you please give me any insight into my problem?

Thank you for your help.
Dear Haibin, In the instructions [here](https://www.synapse.org/#!Synapse:syn6187098/wiki/449445), under the "Execution Bash Script" section, it tells you that you must not only have `#!/bin/sh` and also give the shell script execute permissions by doing `chmod 770 score_sc2.sh` Thanks for your participation. Best, Tom
