Neovim - method textDocument/implementation is not supported

[markfaine]

Code editor

Neovim

Platform

Ubuntu

Version

5.4.3

What steps will reproduce the bug?

It usually pops up as I'm working on a file but I haven't identified the exact operation that causes it to come up. I notice because it very briefly interrupts keyboard input when it comes up.

How often does it reproduce? Is there a required condition?

Unknown, I think it's fair to say at least once every time I edit a .sh file.

What is the expected behavior?

Not sure what textDocument/implementation is meant to do, so I can't say.

What do you see instead?

method textDocument/implementation is not supported by any of the servers registered for the current buffer

Additional information

Not sure but it seems to happen after fixing something identified as incorrect in the script.
