Deno core is not enabled
I have a client who was running a really old version of Windmill (CE embedded in nextcloud) which recently got upgraded to 1.6x. He has flows that were working fine on the older version that are now getting errors that look like this:
InternalError: Error: Deno core is not enabled @worker_flow.rs:2004:11
Same thing is in logs when I got find the logs relative to the flow attempts:

Any tips on what could be causing this?
