AI: StringValueTooLong on Power BI Embedded Report

There were no recent changes to my project; I definitely didn't see this error previously. I'm not sure exactly when this error started showing up but it was within the last few days, and I didn't update my code during that time.

Based on some searching online, it seems pretty clear this error has been thrown in the past due to the dependency ApplicationInsight-JS (https://github.com/microsoft/ApplicationInsights-JS). Apparently when it first caused this error a few years back, it would crash report embedding altogether. I think the embedding-side got fixed so as to not crash, even if the error occurs; on the ApplicationInsight side, apparently some updates 'fixed' it a while ago, but then it reappeared again...and now in 2022 I'm clearly seeing it again. Whatever 'fixes' they are doing don't seem to last very long, it seems!
