We are currently using a rather large stack, which we upgraded to version 7.0 two weeks ago.
After we patched everything and updated the file- and metricbeat, we get the following error message in Elasticsearch:
"Caused by: java.lang.IllegalArgumentException: Cannot write to a field alias [container.image.name]."
I searched for the error, but found nothing useful so far. Do you have an idea where the bug came from and how to fix it?
Many thanks in advance.
