Hey Folks, I am looking for some advice which helps to troubleshoot my issue as i am using lambda authorizer https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-controlling-access-to-apis-lambda-authorizer.html#se[…]api which is attached to authorization part of api gateway. • My problem is that with an HttpApi using a SAM template, it’s not invoking my lambda at all • I get no errors, it just says “Unauthorized” • and fails to invoke the lambda Please help me out as i stuck on this from last 4 days. Great Thanks! for your precious time

If you remove the authorizer altogether, does the target lambda get invoked?

Does HttpApi support lambda authorizer?

Yeah, it does

oooh for some reason I thought it did not

Thanks Ross! I just checked lambda invoked without authorizer

Ok, so that narrows it down. can you add some logging to the authorizer to see where it gets to? Are you returning an IAM policy in the authorizer?

Hi Ross, • regular lambda works • just doesn’t invoke my authorizer lambda

Ok, then it's probably a plumbing problem but not sure about how things work with SAM.
