Thanks for the suggestion, Randy.
Some additional detail: I was originally using conda, and I simplified my environment.yml to the bare minimum. The deployment errored on installing the stream-aggrid module, which is not yet available for installation via ‘conda install.’ Conda needs to install pip to install stream-aggrid. This worked fine on my machine, but it was this step that caused the deployment error.
It was not difficult to switch everything to pip, and that resolved the problem!
Best,
Ben
