Auto-import: invalid type: null, expected struct CodeActionParams

struct A {
    _marker: PhantomPinned, // try to auto-import this, server crashes

Works for me for today's nightly: rust-analyzer version: nightly (b7596d2)

[lnicola]

Tested at 518f6d7.

[SomeoneToIgnore]

Can confirm that almost any auto import fails now on the fresh nightly.

[lnicola]

Probably #6200 CC @kjeremy.

Actually, that doesn't seem related.

[lnicola]

b7596d2 also fails for me.

[max-frai]

Confirm that almost each auto import fails.

[hammypants]

This is also happening for Implement missing members code action for traits. (Which makes sense that it probably uses auto import under the hood.)

[lnicola]

Looks like we're sending an invalid message:

[Trace - 12:26:34] Sending request 'experimental/resolveCodeAction - (54)'.
Params: [
    null
]

[lnicola]

Filed #6213 for it.

[kjeremy]

Good find! Interestingly enough LSP 3.16 will have a codeAction/resolve request.

[matklad]

Yeah, we should switch to codeAction/resolve not sure if it'll square with our groups support though....
