[IbraheemAlSaady]

Description

Specifying the value of integrations variable while having different attributes for each integration results in the error The given value is not suitable for module.api_gateway.var.integrations declared at .terraform/modules/api_gateway/variables.tf:197,1-24: all map elements must have the same type.

Versions

• Module version: 2.2.2
• Terraform version: v1.3.8
• Provider version(s): AWS >= 4.54.0

Reproduction Code [Required]

Here is what I'm trying to run

module "api_gateway" {
  source = "terraform-aws-modules/apigateway-v2/aws"

  name          = "some-api-name"
  protocol_type = "HTTP"

  # Routes and integrations
  integrations = {
    "GET /test-lambda" = {
      lambda_arn             = "arn:aws:lambda:eu-west-1:052235179155:function:my-function"
      payload_format_version = "2.0"
      timeout_milliseconds   = 12000
      authorization_type     = "CUSTOM"
      authorizer_key         = "some-authorizer"
    }

    "GET /test-http-proxy" = {
      integration_type = "HTTP_PROXY"
      integration_uri  = "some url"
      authorizer_key   = "some-authorizer"

      response_parameters = [{
        status_code = 200
        mappings = {
          ....
        }
      }]
    }
  }

  authorizers = {
    ....
  }
}

What I noticed is adding the response_parameters is what's breaking it

You should wrap value with jsonencode() to make all arguments look like strings. See this example:
