Ran into an error that I don't know how to approach. The full report line is:
ERROR |Cannot have multiple factories with the same name. Multiple factories were assigned the name 'blablabla Output Collector'
What does this mean and where should I start looking to solve this? I might ad that this error showed up suddenly. I tried to remove the most recent changes but it persists.
The same thing just happened to me, with FME 2021.2.
In my case, the problematic factory name mentioned in the message was something like “CustomTransformer1_CustomTransformer2_AttributeCreator_3” . There was only one AttributeCreator with the name “AttributeCreator_3” in the custom transformer I was working in.
I ran a few times and the error was repeatable. Eventually I renamed my “AttributeCreator_3” to “AttributeCreator_34265” and the error disappeared. But in your case, I wouldn’t know how to rename an Output Collector.
