I got this issue panic: uuid: Parse(): invalid UUID length: 0

toothsy commented 1 year ago

could you elaborate on how to replicate the panic?

jensilo commented 1 month ago

I guess, I know: uuid.MustParse. https://github.com/google/uuid/blob/0f11ee6918f41a04c201eceeadf612a377bc7fbc/uuid.go#L169

@ahloul use uuid.MustParse very wisely as it panics if the provided uuid.UUID is not parsable. Otherwise, use uuid.Parse and it returns an error if the provided string can't be parsed as UUID.

As mentioned, this is the correct behavior of MustParse. Normally MustParse is used during initialization with fixed strings.
