StringValueTooLong message:"string value is too long. It has been truncated to 1024 characters." props:"{value:/callback#access_token=<token>...} about angular-application-insights

It seems like it's related to the applicationinsights-js underlying package itself, can we see if there's an issue over there - maybe they're working on it - if not we should definitely raise it up to them, maybe it's an easy fix we can get a PR in to fix it over there 👍

I also have this warning.

Using :

• "@angular/...": "~7.2.0"
• "@markpieszak/ng-application-insights": "^7.0.1"

[MarkPieszak]

It seems this may be an existing issue within ApplicationInsights-JS itself, microsoft/ApplicationInsights-JS#286

Are there many tracking events firing off too quickly that's maybe causing this to happen?

[StefH]

This issue is now fixed? microsoft/ApplicationInsights-JS#751

However it's only in the 2.0.0 release, so you plan to upgrade this library to use the new version?

[MarkPieszak]

Ahh I didn't see they moved to 2.0!
Ok let me make the necessary changes - hopefully there aren't too many big ones and I can get an upgrade for the library here.

Just giving some context here from the JS SDK. App Insights limits the length of strings for telemetry. The warning only reflects the app insights world and the actual string is not truncated at all, only in the telemetry will it be truncated.

The referenced fix will not get rid of the warning. It only changed the fact that now the console warning shows the full, untruncated string. Disabling verboseLogging (or the equivalent for this SDK) should suppress the warning after the first time, but there doesn't seem to be a way to prevent it altogether.

For the 2.0.0 SDK, you can use the new consoleLoggingLevel config option and set it to 0 (this is the default) to disable all SDK console warnings from our end.
