Overflow value(exceeding uinteger) passed into jsonrpc but still work

[He1pa]

The reason is that I found that the fmt feature of my lsp server cannot be used in IntelliJ, but it still work in vscode.
After investigation, I found that I assigned a u32:Max to formatResponse.textedit.range.line in the format's Response
I implemented the lsp server in rust, and u32 was used as the range type in rust's lsp-type, but the range of this value in lsp should be 0-2^31 -1. I think this is the cause of the problem

But I'm not sure whether vscode has special handling for this situation or just forgot to check

kcl-lang/kcl#1698

VS Code doesn't currently have checking code for this.

I ran into this as well. If VS Code detects this what should it do? 🤔

The only way how we could handle this is IMO by returning it as a Response error and then report it on the other side via an Error.
