Hi,
I was trying to store some waveform data using The EPICS Archiver Appliance, but the storage failed.
The PV names of the waveform data are as follows:
AC-LA-INJ1-BI:SBPM02-E:CH4_RAW_WAVEFORM
The error message is as follows:
61369 [JCA Command Thread] ERROR org.epics.archiverappliance.engine.pv.EPICS_V3_PV - While processing a handleConnected for AC-LA-INJ1-BI:SBPM02-E:CH4_RAW_WAVEFORM.SCAN; the channel is not in a connected state.

I don't think there is a problem with the data storage system, other types of data can be stored normally. The server can also obtain data normally, what causes storage failure?
