Code

This error occurred when running tests cargo test --all --all-features for foundry at commit 249538faaaee2d916b656829fdd82815d4c46a55
According to the error message, the panic is at the Ok(()) in the code snippet below.

Unfortunately, my lack of Rust knowledge prevents me from providing any further guidance here. I'm happy to help troubleshoot / respond to any questions.

[CyMule]

This is probably a duplicate of #107440 ?

[clubby789]

#107678 I think, given that the error is in compiling combine. This has been fixed on master, so updating your nightly version may fix this.

@clubby789 looks like you were correct! updating did work
