Oh3 Expert Mode cannot be accessed

Setup, Configuration and Use Items & Sitemaps

Hello,

due to a crash during a data backup (power failure) I have the problem of having to rebuild my entire NAS. Openhab 3.4.2 must also be completely reinstalled. It is very difficult because the previous fuse was also destroyed. I’m currently trying to fix a bug that I need help with. If the Expert Mode should be opened when creating items from Things, this error message appears:

openHAB
There was an error generating the items definition: TypeError: u is undefined

Can someone help me to eliminate this error?

I’ve never seen that “expert mode” option before. Is this something you’ve used before and it works? What’s it do?

I’m on the OH 4 snapshots and it doesn’t work for me. I get only a slightly different error.

There was an error generating the items definition: TypeError: Cannot read properties of of undefined (reading $oh)

Nothing appears in my openhab.log.

I can’t say if it’s a regression or if it’s an incomplete feature. But I recommend following How to file an Issue on the openhab-webui repo.

Looks like it’s a regression from this PR.

Cool, I’ll go ahead and file an issue for this one since I’m on the latest and can reproduce the error.

Same failure on 3.4.2
