Lambda@Edge

503 ERROR

The situation • I have a Cloudfront Distribution and defined

defaultCacheBehavior.lambdaFunctionAssociations

to trigger a lambda on

origin-request

. • Weirly enough, there is no trigger in the lambda function overview, it says "+ Add trigger". I am not sure if I am missing iac here at some point. The Problem When I open the url, I get an

503 ERROR

. What I tried • There are some logs written to s3 (linked in CloudFront > Telemetry > Logs > S3 Bucket) , but the only valuable information I read out of it that there was a

LambdaExecutionError

. • If I go to the Lambda@Edge Function and click in Monitoring and then View in CloudWatch, it says

Log group does not exist

. Can anybody point me into the right direction? Many thanks in advance
