Parse error reported while restarting the server

[July541]

Open a Haskell project and then restart the server with the restart command, I got the following error:

Maybe related to #920.

I'm not sure if there has an alternative method instead of comparing the jsonrpc message for different client versions...

Can you retry with the options Haskell > Trace > Server set to Messages? It should contain the LSP messages that are sent from the client.

Can you retry with the options Haskell > Trace > Server set to Messages? It should contain the LSP messages that are sent from the client.

I've downgrade languageclient to 7.0.0(our original version), and can't repro #920, so #920 doesn't relate to HLS upgrade, #920 and this issue are separated.
