Error from Companion: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference

I don't see anything unusual.

I get the same error on the code server with a current Companion.

Your empty Firebase projectbucket is suspicious.

What do you see in your Firebase console for database contents?

i`ve tried to put it like this, so the ProjectBucket is not empty. Same error appear.

Which Firebase server region do you use?

The AI2 Firebase component only works on us-central.

in case I forgot something.

Bedtime here at GMT-5, maybe GMT 0 will be up soon.

A late hunch ..

Firebase data written by the AI2 firebase component usually appears in the firebase console with extra markup, quotes and back slashes.

AI2 needs that to reconstitute data type info.

Your data lacks that markup, as if you hand typed it in the firebase console.

Flush it out, and use the firebase component to add fresh data.
