Cloudwatch event rule triggered by AWS ECR event

Hello.
I am trying to setup CI/CD with AWS codepipeline and now I am stuck with pipeline autostart.
Looks like cloudwatch does not detect ECR events so does not start a pipeline.
Target and role configured correctly, but in access advisor for role I don`t see any role invocations.
Region us-west-2.

Here is event pattern that I use:
{
"detail": {
"eventName": [
"PutImage"
],
"requestParameters": {
"imageTag": [
"service.develop.latest"
],
"repositoryName": [
"repository"
]
}
},
"source": [
"aws.ecr"
]
}

I can see PutImage events in cloudtrail but this rule does not work. Any help appreciated, thanks.
