@darenkeck-dev See my comments:

• The ES version should be updated if we want to use the at()method.
• The other one is more a question related to the requirement to organize templates by library.

@AntoineGautier changes have been made hiding any visible update in the client UI. This is ready for review again.

@darenkeck-dev Tests failed with 2872fce because of the following break in the JSON file path discovery:
https://github.com/lbl-srg/ctrl-flow-dev/blob/main/server/src/parser/loader.ts#L180-L186
Do you remember the rationale to have getPathFromClassName return null in case typeStore.has(modelicaPath)?
This seems like breaking the proper separation of concerns between:

• the function getPathFromClassName that should always try to return the path to the JSON file if it exists,
• any caller of getPathFromClassName that should check that the file has already been loaded before loading it again.

I would be willing to remove this check from getPathFromClassName (for now, I've just moved it after the package path discovery). What do you think?

(I pushed a fix for stopping the discovery process after processing the root package.)

Regarding the changes from dk/455-nested-systemtypes, I tested loading two test packages with server/scripts/parse-test-package.ts and validated that configuration parameters specified in the UI are properly included in the payload with getSequenceData().
I also tested that dk/455-nested-systemtypes produces the same sequence document as the main branch for the same set of parameters.
