I’m trying to modify the data-connector-example code to import issues from Linear rather than folders, and show them in the data linking panel in the same way, with parentId.
I could get OAuth to Linear and getting the data from it to work fine, code at https://github.com/ShoggothAI/sample-lucid-extensions/tree/linear/linear-connector-example

However when the code tries to insert the data so it’s visible in the  Data Linking Panel, I keep getting the error

The code there is as similar to the one for importing Lucid folders in the example as I can make it, yet the latter runs fine and this one breaks. Any idea how to fix that?
Thanks a lot!
