Unable to create forwarder module in regions other than us-east-1

[qpre]

when trying to use the module using aws provider with regions like eu-west-3 the zip for the lambda is not reachable.

InvalidParameterValueException: Error occurred while GetObject. S3 Error Code: PermanentRedirect. S3 Error Message: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.

as I'm guessing the lambda from us-east-1 won't forward logs from CW groups in eu-west-3, is there a way to circumvent this ?could the lambda zip directory be shipped with the module ?

hi @qpre. I will try to reproduce, the zip file should be accessible from anywhere, will double check.

As for your question, yes forwarder lambda have to be in the same region as the CW groups.

I tried to access the zip file from the browser and it works, so I doubt thats the issue. Can you show an example code of your module?

Hey, thanks for your answer

I tried to access the zip file from the browser and it works, so I doubt thats the issue.

it's normal that it works in a browser because you already have an url for the asset, what does not work is here:

resource "aws_lambda_function" "forwarder" {
  s3_bucket     = var.lambda_zip_bucket
  s3_key        = "axiom-cloudwatch-forwarder/v${var.lambda_zip_version}/forwarder.zip"
  ...
}

when deploying a lambda with an s3 asset, the asset must be in the same region as where the lambda is deployed.

Can you show an example code of your module?

module "axiom-cloudwatch-forwarder" {
  source           = "axiomhq/axiom-cloudwatch-forwarder/aws//modules/forwarder"
  axiom_dataset    = axiom_dataset.cloudwatch.name
  axiom_token      = axiom_token.cloudwatch.token
  prefix           = "forwarder-${var.environment}"
}
