How to fix Error: Error creating Elastic Beanstalk Environment: InvalidParameterValue in Terraform

Check the AWS Elastic Beanstalk console to confirm your environment status:

1. Navigate to Elastic Beanstalk in AWS Console
2. Click on your application, then the environment name
3. Check the Status field - it should show "Ready" in green
4. If status is UPDATING, TERMINATING, or CREATING_FAILED, wait for it to stabilize or terminate and recreate

If the environment is stuck in a failed state, you may need to delete it and create a new one.

If you're using Terraform with AWS provider version 4.63.0 through 5.72.x, upgrade to 5.73.0+ to get the fix for simultaneous settings and tag updates:

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = ">= 5.73.0"
    }
  }
}

Then run:

terraform init
terraform plan
terraform apply

Check that the solution stack you specified is available in your AWS region:

data "aws_elastic_beanstalk_solution_stack" "app" {
  most_recent = true
  name_regex  = "^64bit Amazon Linux 2 .* running Node\.js.*$"
}

resource "aws_elastic_beanstalk_environment" "app" {
  solution_stack_name = data.aws_elastic_beanstalk_solution_stack.app.name
  # ... other config
}

Alternatively, query available stacks:

aws elasticbeanstalk describe-platform-branches --region us-east-1 --output table

If you cannot upgrade the AWS provider immediately, split environment settings and tag changes into separate Terraform applies:

# First apply: settings only
terraform apply -target=aws_elastic_beanstalk_environment.app

# Wait a few minutes for environment to stabilize

# Second apply: tags
terraform apply -target=aws_elastic_beanstalk_environment.app_tags

Or manually separate them in your configuration to ensure they don't apply together.

Ensure any referenced application versions and configuration templates exist:

# List available application versions
aws elasticbeanstalk describe-application-versions \
  --application-name my-app \
  --region us-east-1

# List available configuration templates
aws elasticbeanstalk describe-configuration-settings \
  --application-name my-app \
  --region us-east-1

Remove references to non-existent versions from your Terraform configuration.

Verify the underlying CloudFormation stack is healthy:

aws cloudformation describe-stacks \
  --stack-name awseb-<environment-name> \
  --region us-east-1 \
  --query 'Stacks[0].StackStatus'

If the status is CREATE_FAILED or ROLLBACK_COMPLETE, the Elastic Beanstalk environment cannot recover. You must terminate the environment and create a new one:

aws elasticbeanstalk terminate-environment \
  --environment-name my-env \
  --region us-east-1
