It's not the same error than in my app thought. It's failing with

Hello @gsmet ,

Do you know who can help me with that ?

I can try to draft a PR but I need some insight on how the hot reload mechanism is designed. I'm not sure where I should start.

I reported a similar issue with #17747
Would love for this to get fixed/implemented!
