I've been dealing with this TailReader error for a while and was not able to fix it despite reading all answers and similar questions. I'm still experiencing data loss every day.
As you can see in below .confs I already disabled indexed_extraction since the universal forwarder doesn't extract field at index time, but still getting that error.
I was told to migrate to a heavy forwarder, but I prefer to solve it on UF if possible.
I appreciate any help.
