AWS EventBridge Event not triggering lambda function with proper permission-CodePudding

I have an eventbridge rule and it's configured with a lambda as a trigger. The eventbridge rule is a time based cronjob, I'm facing an issue with the eventbridge that it's not triggering the lambda function. I came across few answers and added lambda:InvokeFunction permission on lambda to the role but it's still not resolved yet.

Can anyone help me on this? The policy is added as part of terraform aws_lambda_permission to the lambda function. The lambda function is written in .Net

My terraform policy looks like this -

resource aws_lambda_permission allow_lambda_invoke {
  statement_id  = "AllowExecutionFromEventBridge"
  action        = "lambda:InvokeFunction"
  function_name = aws_lambda_function.account_derive_and_publish_notes_handler.function_name
  principal     = aws_iam_role.account_lambda_role.arn
}

CodePudding user response：

For EventBridge, principal should be events.amazonaws.com, not your function ARN.
