1074118441 errors during an RFSA spectrum acquisition

My business is utilizing the 566x Vector Signal Analyzer to perform a spectrum acquisition. It usually works, but a couple of errors involving Digital Edge have been triggered recently:

Error -1074118441 occurred at niRFSA Read Power Spectrum (Cluster).vi
A possible reason (s): These kinds of errors are not supported when the acquisition type is set to spectrum.

Why do I receive this specific error?

This trigger type is not supported when the acquisition
