My Garmin activities fro 4/11/23 are not uploading at all. I disconnected Garmin and tried to re-establish the connection but I get the following error message:
{“status”:500,“error”:“java.lang.IllegalArgumentException: argument “content” is null”}
So I think something with Garmin is broken. It worked fine for my activity yesterday.
Probably best to just download the fit file from Garmin Connect and manually upload it to Intervals.icu. Future activities will probably work. Garmin make it hard to get old stuff.
