Hi:
I am running filebeat 7.15.0 to process S3 object creation event messages from AWS SQS. The queue is configured to receive AWS ELB log files. After a few minutes, filebeat 7.15.0 crashed with the following error.
The same program used to work fine with filebeat 7.14.1. This crash happened after I upgraded filebeat from 7.14.1 to 7.15.0
panic: runtime error: invalid memory address or nil pointer dereference
