Roundtrip Issue: Can't go from text mode to form node when a workspace node is unknown

How are you using Studio?

Legend Studio

Current and expected behavior

Our team is currently working with adding MongoDB support in legend.

The mongodb store workspace node has the header ###MongoDB.
Given the new studio functionality, we can write in text mode the mongodb workspace nodes, including the store, and we can compile it successfully.

Current behavior:
After compiling all the workspace nodes in text mode, it is not possible to go to form mode. When attempting to go back to form mode, all the workspace nodes disappear, unless they have already been pushed to gitlab, in which case they appear in text mode, but the store is being dropped.

Expected behavior:
After compiling all the workspace nodes in text mode, it should be possible to go to form mode.

Steps to reproduce

• Start the Legend Engine on master branch, and start the SDLC and Studio (if you develop locally).
• Create a new workspace or use an existing one in Studio.
• Go into text mode and paste the workspace nodes from the Model Data below.
• Click F9 to verify it compiles successfully.
• Now you can either try to go to form mode directly, or push it to gitlab first and then go to form mode. Ideally you should try both flows, since if the workspace nodes aren't on gitlab they disappear, while if they are on gitlab they appear but drop the store workspace node.
