SAM Local Invoke: Layer endpoint not found

0

Hi,
I'm trying to set up a local dev environment for my Lambda functions using SAM. I had everything working until I added a reference to a layer in my configuration.

I followed the instructions here: https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-layers.html. I added my ARN for my layer version in my template.ymal (image attached). However when running a "sam local invoke" I get an error stating "EndpointConnectionError: Could not connect to the endpoint URL" (screenshot attached).

The way I've added the ARN in the configuration seems to be exactly how they do it in the example so I'm not sure what is causing the error.

Hi,
Note: I haven't tried adding the Layers based off of the link you provided (so apologize in advance if you wanted help with this specific method). However, I was able to successfully follow the directions in the following link:
https://aws.amazon.com/blogs/compute/working-with-aws-lambda-and-lambda-layers-in-aws-sam/
which allowed me to create a lambda layer and invoke it locally from my desktop.
Hope this helps,

Hi Randy,
Thanks for trying this. Both articles seem to use the same method of adding the Layer Version ARN to the template.ymal.

The URL it is trying to connect to doesn't look right: "https://lambda.eu-west-1a.amazonaws.com/2018-10-31/layers/arn%3Aaws%3Alambda%3Aeu-west-1%3A326436164324%3Alayer%3AGlobal/versions/7". Does your output show the Layer endpoint URL when running the local invoke command? If not would you be able to change your Layer ARN to something random to attempt to recreate the error so I have another URL to check mine against?

Kind regards,
Darren

I've found the issue. My ~/.aws/config file had the region set to "eu-west-1a" when it should have been "eu-west-1".

Thanks! That was the problem for me too.
