yarn start inside a script failed with error Could not write file

[olechnwin]

Hi,
I am trying to run yarn inside a script as follows:

sbatch --time=10:00 --wrap "singularity exec $momig_frontend_img bash -c 'cd /opt/MoMI-G && yarn start'"

but got this error:

yarn run v1.22.10
$ react-app-rewired start --scripts-version react-scripts-ts
error Could not write file "/opt/MoMI-G/yarn-error.log": "EROFS: read-only file system, open '/opt/MoMI-G/yarn-error.log'"
error An unexpected error occurred: "EROFS: read-only file system, mkdir '/gpfs0'".

However, the following command works:

singularity exec $momig_frontend_img bash -c 'cd /opt/MoMI-G && yarn start'

What do I have to do to run yarn start inside a script?

Thank you in advance for your help.

From which user are you executing the script? And what exactly is singularity? Also, are you sure, the cd Is actually being run? Since both scripts should not work, when the file system is being under „Read-Only“.

Thanks for your help. I'm running the script as a user not root if that's what you're asking. singularity is a container just like docker so I'm running it inside a singularity container which contains its own OS.
I'm pretty sure the cd is being run because I have the yarn installed in /opt/MoMI-G.
That's what confuses me, I thought both commands should not work if the file system is under "Read-only"

Looks like a filesystem error instead of a Yarn error.
