Just as a note in 7:51 the runtime handler is not the name of the function entry point, but the name of the executable generated by go build command. For example if you run "go build something" the runtime handler must be "something".

Hey there! When I try to run my program locally, I get the following error: expected AWS Lambda environment variables [_LAMBDA_SERVER_PORT AWS_LAMBDA_RUNTIME_API] are not defined. I find this weird since the AWS Lambda documentation does not mention any env variables with these names, nor mentions this configuration step at any point. I already tried googling for it but I got no answers. Do you know if there's something I'm missing? Thanks in advance!

That is strange... honestly to do local testing, I use AWS SAM which kinda takes care of that logic. You might find some answers here: docs.aws.amazon.com/toolkit-for-vscode/latest/userguide/welcome.html

@sergeyagronov9650 Жыл бұрын

the handler name is the file name, not the function name like u mentioned in 8:00

@sherifhmdy Жыл бұрын

exactly it's the binary file name generated from the build command I believe. But anyway thanks a lot @Brian you helped me to create my first lambda function.

How can I pass parameters such as bucket name, path etc

@brianmmdev Жыл бұрын

If you're using an S3 event, you'd want to replace the event param with `s3Event events.S3Event`. I do this in my side project, you can see more here: github.com/GuardianForge/guardianforge.net/blob/0f6b41f1bcf28830557510496f8d3ea19939d06e/backend/stack/s3-handlers/create-og-image/main.go#L52C35-L52C57

@BrianMorrison Lambda "Test" returned "fork/exec /var/task/main: exec format error: PathError null" when I built with v1.17 or v1.20. Log Events said "INIT_START Runtime Version: go:1.v15". OK I understand that, but.. How are you using v1.17 under Lambda in 2022, when in 2023 the steps in the video cause AWS to look for v1.15? Did you also customize something in Lambda (allowing 1.17) which wasn't covered here?

@brianmmdev Жыл бұрын

Nothing funny going on that wasn't covered. Maybe it's a regional thing? What region are you trying to deploy to?

This problem is because in 7:51 he says that the handler name should be the name of the function entry point "main", but in reality it is the name of the executable generated after the go build process. For example if you create a go project named "lambda-something" and inside it you run "go build" the executable name is "lambda-something" so that is the name you should put in the runtime handler not main.
