I found the root cause, in the OPC Adapter, there was a tag named "Air Quality". I removed it with a Projection Processor and then I was able to deploy the pipeline. After renaming the field from "Air Quality" into "AirQuality" in the OPC Adapter, I can include all tags and remove the Projection Processor. That means that the Trend processor doesn t support objects with a space in the name.
