Workflow editor: tool boxes collapse (randomly) and toolform gets empty

[bernt-matthias]

Describe the bug

While working on galaxyproject/iwc#321 I observed the following (which I can't describe well with words):

workflow-2024-01-11_23.17.05.mp4

Before starting the video I created the tool a few times (1-2x) without problems. At some point the effect happened apparently at random.

Galaxy Version and/or server at which you observed the bug
Galaxy Version: 23.1
Commit: 0e3a0ca

To Reproduce

See video

Expected behavior

Tool box and form are always visible.

Can you open the browser console and see what's wrong there, and also check your galaxy log ? One way to see this is if your server has an inconsistent toolset, e.g one process doesn't have the latest version of a tool, and the version it has can't work with the parameters you're sending.

Problem went away with restart. So probably the same root as #17273

We're missing an error handler though, we should at least display that something went wrong.
