SOLVED Use of undeclared identifier 'tmperr_ies'

I'm trying to get my plugins up and running with the new serialisation scheme of R21.
But, when I type this:

maxon::String prodID,sysID,userID,licenseID, userName;
GetGeneralLicensingInformation(prodID, sysID, userID, licenseID, userName) iferr_return;

I get an error in the "iferr_return;" and the error is: Use of undeclared identifier 'tmperr_ies'
What could be going wrong?
I'm on Mac OS 10.15.1, Xcode 11.2.1

Hi Rui, thanks for reaching out us.

With regard to the issue you mention, it's caused by the fact that the iferr_return statement requires the tmperr_ies identifier to exist. This is usually managed by adding the iferr_scope; at the beginning of the code fragment where error handling is involved (usually at the very top of the function/method implementation).

Error handling is properly explained in this manual but mostly important have a look at the Error Scope section.

Best, Riccardo

Thank you very much, RIccardo.
I will look into it tonight when I get home.
