   = note: the following trait defines an item `TYPE`, perhaps you need to implement it:
           candidate #1: `Trigger`

Thanks. It looks from the lockfile as if the code was written against Spin 2.8, but the Spin crate reference is not pinned, so when your Cargo.lock updated, the version drifted. I will update to 3.2 and pin it.

It looks like the locked version of time is mad at us too.

I was able to build my own and able to install its plugin.
Working well!
