tw pipelines update not working for pipelines under shared workspace

[markpanganiban]

When trying to update the pre-run script of a pipeline within the shared workspace, we get the null pointer exception error like below:

$ ./tw-0103 pipelines update --workspace 227623619488801 --id 248858957179140 --pre-run prerun.txt

This issue doesn't happen on a pipeline within the private workspace.

This might be due to the shared pipeline not having a compute environment selected.
