error when upgrading to Iris

[umbundu]

Greetings,
When we try to compile the Log class for (IRIS-based) HealthShare 2022.1. we get the following error:

Error: MPP5646 : ##expression on '##class(App.Log).GetMethodArguments(%classname,%methodname)' failed with an error: 150 zGetArgumentValue+1^App.Log.1 %Library.CacheStorage

Any thoughts?

Thanks,
Everardo
