Looking into an issue with CI here:

Error when evaluating 'strategy' for job 'build'. .github/workflows/extensions.yaml (Line: 66, Col: 15): Matrix must define at least one vector

CI appears to be passing, but if we look closer we can see it's not detecting the expected changes and failing to run the build and test steps. @joshuajerin could you update the name of trunk.toml to Trunk.toml? I think that may be causing the CI issue here.

Hey @joshuajerin , bumping this :)

changed from trunk.toml to Trunk.toml

@joshuajerin Thanks for updating that file! That seems to have helped trigger the rest of our CI jobs. The bad news is they are both failing.
