Rust Analyzer randomly panicing.

[augustocdias]

I'm having this error popping up randomly on neovim and always when that happens I have to restart rust analyzer to have it working again:

   Error  16:50:51 notify.error rust-analyzer: -32603: request handler panicked: Can't find FN@0..364 in AstIdMap:
[SyntaxNodePtr { kind: MACRO_ITEMS, range: 0..684 }, SyntaxNodePtr { kind: FN, range: 0..363 }, SyntaxNodePtr { kind: FN, range: 363..684 }, SyntaxNodePtr { kind: BLOCK_EXPR, range: 158..363 }, SyntaxNodePtr { kind: BLOCK_EXPR, range: 469..684 }, SyntaxNodePtr { kind: MACRO_CALL, range: 173..256 }, SyntaxNodePtr { kind: BLOCK_EXPR, range: 496..682 }, SyntaxNodePtr { kind: BLOCK_EXPR, range: 502..681 }]

Analyzer version: rust-analyzer 0.3.2129-standalone (822644d 2024-09-29)
Rustc version: rustc 1.83.0-nightly (363ae4188 2024-09-24)
Cargo version: cargo 1.83.0-nightly (eaee77dc1 2024-09-19)

I'm not sure how to reproduce... I'm editing the code on this repo/branch: https://github.com/wireapp/core-crypto/tree/feat/transaction
Maybe it is because it has a lot of errors due to a lot of refactoring that is ongoing there, but it is happening quite frequently.

Does it have a backtrace in the logs? Also, what file were you editing?

[augustocdias]

It was crashing with different files. I couldn't find any pattern... I still have to face it again to see if there's any backtrace. I forgot to look into. Do I have to specify any config to rust-analyzer to generate it, or it will do by default?

[ChayimFriedman2]

It should generate backtraces by default when panicking. They will be at Output>Rust Analyzer Language Server (in VSCode, not sure about other editors).

Now that the error to happen, it doesn't anymore... Mayte it was solved in the last releases... I'll keep an eye on it and if it happens I'll update this issue. Feel free to close it for now.
