Bootstrap: log shows: user.debug weewxd: GaugeGenerator: Cannot decode reading of 'None' for gauge 'windDir'

Most of it’s in the subject line.  The log before/around this looks like:

..followed by many more identical lines.

I’m running weewx v 4.1.1, with v2.26 of Nick Dajda’s Bootstrap extension (fuzzy archer) on a Raspberry Pi running Buster, and Davis Vantage Vue.  Default python version is 3.7.3, though the log tells me that weewx is using 2.7.16.

I haven’t yet gone climbing to exercise the weather station, but the archive table in the database appears to contain sensible (changing) values for windDir.

Thanks for any help.
