Which commit did you take the config file from?

Would it be possible not to duplicate config.js between scicatlive and frontend? Or else use a very minimal config, where any unchanged values are omitted? Right now we frequently have big changes between config.js between frontend branches, making it hard to migrate the scicatlive configuration without causing merge conflicts. My current dev workflow is (1) build containers (2) stash changes, which are usually just config.js (3) check out the new branch, (4) stash pop.

Ahh, seems to be from the current master (last changed in 9f90abd)

I'm approving this since we need constancy with the frontend, but it would be nice to have a long-term solution.

I inspected it in the browser and the console was giving me an error for missing defaultDatasetsListSettings, which then I realized comes from here.

I think one problem of scicatlive is that it always runs entrypoints scripts, which for the FE includes the configs merging, while it should only run them once when the container is created. I will open an issue for that
