I am facing this issue as well. I have noticed this happens anytime chat completes it's generation. This could be after calling :TabnineFix or :TabnineExplain

[aarondill]

we could bandage this by giving a nicer warning when json decoding fails (i've been wanting to do this for a while actually), but the actual problem lies in the chat binaries outputting non-json (which is proprietary code, so someone on the TabNine team has to fix it)

@allan-simon is this still happening? can you share a video of the issue? is it with /generate-test-for-code?

[amirbilu]

@mumahmud can you please check if you're able to get tabnine chat working now

[amirbilu]

closing this as fixed. feel free to re-open.

Can we get this re-opened.

I just setup chat today and this issue reproduces fairly consistently for me when using /explain-code
