Unable to remove the EventBridge trigger in Lambda function

Question

Why can't I remove the Eventbridge trigger in my Lambda function configuration if the rule has already been deleted in Eventbridge? When I click on 'Delete', it shows me the same screen.

Hello.

In that case, try running the following command.  
When you run the command below, you can check the "Sid" in the response.  
```
 aws lambda get-policy --function-name test
```
Below is an example response.  
In the following response, "Sid" is "lambda-yyyyyyyy-yyyyyyyy-yyyyyyy".  
```
{
    "Policy": "{\"Version\":\"2012-10-17\",\"Id\":\"default\",\"Statement\":[{\"Sid\":\"lambda-yyyyyyyy-yyyyyyyy-yyyyyyy\",\"Effect\":\"Allow\",\"Principal\":{\"Service\":\"events.amazonaws.com\"},\"Action\":\"lambda:InvokeFunction\",\"Resource\":\"arn:aws:lambda:ap-northeast-1:1111111111:function:test\",\"Condition\":{\"ArnLike\":{\"AWS:SourceArn\":\"arn:aws:events:ap-northeast-1:111111111:rule/test1\"}}}]}",
    "RevisionId": "yyyyyyy-yyyy-yyyy-yyyy-yyyyyy"
}
```
Once you have confirmed the "Sid", you can delete it by specifying the Sid with the command below.  
```
aws lambda remove-permission --function-name test --statement-id lambda-yyyyyyyy-yyyyyyyy-yyyyyyy
```

Hi,

Is your user allowed to delete EventBridge resources? Check with CloudTrail to see if you've a permission issue there?

Best,
