I’ve picked up and old JavaScript project that was deployed using ClaudiaJS and I’m converting it to use SST. In time, I need to rewrite it in TypeScript but for now I just need to get it up and running. I’m running into a problem when the endpoint is called which just says

ERROR build_failure: The function src/handlers/lambdaHandlers.bookAppointmentHandler failed to build

I can’t find any more information anywhere on what it was that caused the build to fail, where should I be looking?

This looks like a problem I before with the details of a build failure being swallowed up by SST. I found it by adding console logging in the SST code where it forks out to build. I thought the SST team fixed that, but now don't recall.

there is also a debug log in the

.sst

folder

Yeah, the debug log didn’t show anything more than what was printed in the console

@Ross Coundon what ended up being the error? Let me recreate that on my end and figure out how to expose the error.

there is a rare case I haven't been able to track down where ebsuild exits without printing an error

I changed a bunch of things as I went through the code, it’s possible it was down to changing a require to an import there and a missing reference to a function.

I see. Opened an issue to track this https://github.com/serverless-stack/serverless-stack/issues/1486

I mean, the real answer is, don’t use raw JavaScript 😄
