(BadMapError) expected a map, got: nil

In my next-ls log when starting Zed I get this:

Same here. This is how the error looks in the overall logs:

2024-08-13T10:11:49.212501Z [ERROR] failed to format via language server

@PJUllrich to be fair, your error is clearly different from the OP's one. It might make sense to file a separate issue.

Getting the same as @dan-klasson.

[PJUllrich]

@xmyst it's the same error, just viewed from a different log file. OP showed the error from the LSP's log file whereas mine is from Zed's log file.

@mhanberg in the light of the merge of the 3 language servers, what should we expect to happen with this issue? thanks
