GUID function fails to convert to string

[peter_c]

Recently the conversion of the value from a GUID function to a string has stopped working. 

For example, if you add a Label to a form and set its Text property to: "Text " & GUID(), it now reports the error: "Invalid argument type. Expecting one of the following: Text, Number, Boolean."

You can use the Text function to convert from the GUID value to a string in this case:

"Text " & Text(GUID())

Thanks Carlos.  This does resolve the issue, however, my main reason for raising it is because it's a breaking change and the documentation also doesn't reflect this change yet (https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-guid).
