Log filling with PGN read errors

[preeve9534]

My Signal K log is filling with the following error messages, approx 1 per 30s or so.

I am guessing that my bus includes a PGN that canboatjs can't parse (or maybe not).

Question is: is the verbosity of log output for this type of problem appropriate? Line 2/3 in the log snippet below suggests that the error is in any case being generated in a peculiarly unhelpful way since it doesn't give a place to look for the problem.

I'm happy to help tracking this down or to provide more data.

Hi,

do you still have this with a fresh nodeJS16 based Version 1.41.3 ?

For me a PGN can not be mapped. CanboatJS - Undefined PGN 60928 #1423
