FailedInvocation when connecting eventbridge to glue workflow


I set up the resources to trigger glue job through eventbridge. But when I tested in console, Invocations == FailedInvocations == TriggeredRules == 1.

What can I do to fix it?

######### AWS Glue Workflow ############
# Create a Glue workflow that triggers the Glue job
resource "aws_glue_workflow" "example_glue_workflow" {
  name        = "example_glue_workflow"
  description = "Glue workflow that triggers the example_glue_job"

resource "aws_glue_trigger" "example_glue_trigger" {
  name = "example_glue_trigger"
  workflow_name =
  type = "EVENT"
  actions {
    job_name =

######### AWS EventBridge ##############
resource "aws_cloudwatch_event_rule" "example_etl_trigger" {
  name        = "example_etl_trigger"
  description = "Trigger Glue job when a request is made to the API endpoint"

  event_pattern = jsonencode({
    "source": ["example_api"]

resource "aws_cloudwatch_event_target" "glue_job_target" {
  rule      =
  target_id = "example_event_target"

  arn = aws_glue_workflow.example_glue_workflow.arn
  role_arn = local.example_role_arn

I understand that you are trying to trigger Glue Workflow using EventBridge, however rule was failing to invoke the target.

  • TriggeredRules metric indicate that the rule matched an event and forwarded the event to the target.
  • Invocations metric indicate that the target was invoked by the rule
  • FailedInvocations metric indicates that there is an issue invoking the target.

FailedInvocations represent a permanent failure and might be the result of incorrect permissions or a misconfiguration of the target. I kindly request you to make sure the target IAM role has required permissions. Please refer the following documentation to learn more about IAM permissions.

[+] Starting an AWS Glue workflow with an Amazon EventBridge event

Further, make sure your IAM role also has following "Trust relationship" policy attached.

"Version": "2012-10-17",
"Statement": [{
    "Effect": "Allow",
    "Principal": {
        "Service": [
    "Action": "sts:AssumeRole"

You can also consider configuring a dead-letter queue (DLQ) to troubleshoot/ debug the failed invocations issues/ avoid losing events after they fail to be delivered to a target and send all failed events to it for processing later.

For detailed investigation, we would need to check the resources and the permissions in your account. If you still have queries regarding this, I would like to request you to reach out to our support team by opening a support case with all the resource details, and we will investigate the issue further.

Let me know if you have any further queries. Thank you for your interest in re:Post community.
