Error: Call to function "merge" failed using cloudfront_origins

[jagarzonhuge]

Using the input cloudfront_origins results in a terraform error:

Error: Error in function call

  on .terraform/modules/tf_next/main.tf line 173, in locals:
 173:   proxy_cloudfront_origins = var.cloudfront_origins != null ? merge(
 174:     local.next_image_cloudfront_origins,
 175:     var.cloudfront_origins
 176:   ) : local.next_image_cloudfront_origins
    |----------------
    | local.next_image_cloudfront_origins is list of object with 1 element
    | var.cloudfront_origins is list of object with 1 element

Call to function "merge" failed: arguments must be maps or objects, got "list
of object".

Are you able to share what you passed as argument?
It's not very well documented (since we will provide a better solution for it soon #55) but it requires a very specific format in order to make it work.

I tried with an empty list [] and with this:

cloudfront_origins           = [{
    domain_name: aws_s3_bucket.storybook.bucket_regional_domain_name,
    origin_id: local.s3_origin_id,

    s3_origin_config: {
      origin_access_identity: "origin-access-identity/cloudfront/XXXXXXXXXXXXXX"
    }
}]

As the error message says, the module is trying to merge 2 lists of objects but the merge function only works with maps/objects

[ofhouse]

We use it internally so I can definitely confirm that it works under normal conditions 😁

Object notation seems incorrect here, = instead of : should be used to separate key/values:

cloudfront_origins           = [{
    domain_name = aws_s3_bucket.storybook.bucket_regional_domain_name
    origin_id = local.s3_origin_id

    s3_origin_config = {
      origin_access_identity = "origin-access-identity/cloudfront/XXXXXXXXXXXXXX"
    }
}]

@jagarzonhuge Were you able to solve the issue or does the problem persist?

This has been fixed in v0.7.4.
