Good question.
As you wrote, preview thumbnail errors should not impact production outputs going to other targets. The thumbnails for output preview get written to a bucket owned by the MediaLive service, not a customer bucket. Every PUT attempt to S3 gets 3 retries, so one write error is not necessarily a failure on that file.
There are some possible conditions which might cause an S3 write error:
- If the channel is running in a VPC, then the VPC needs an S3 access endpoint or some other means of reaching the output bucket.
- some issue with the IAM Role MediaLive assumes to run the channel in your account
- Other transient error reaching S3, possible dependency outage, or service outage etc.
If you want a deeper investigation, the S3 support team can trace the individual S3 request IDs for each PUT operation. I suggest opening a case with AWS Premium Support to start that process.
This answers the question. Thank you.
Because I was following the guide's "complex option", I did not give broad access to S3.
I'll use the "Feedback" link on the Trusted Entity Requirements page to request that the ARN of the MediaLive bucket be included on that page so it can get included in custom policies.
