In the TDM Portal I am able to reference an XSD file. However, when I click on the object, an error which references %CATDMWEB_APPDATA% appears.
I was receiving a similar error in invoking a Javelin flow via the Portal. How can I resolve this issue?
Issue is that the installer was not able to initialize the variable, and as a result, the value was left as undefined. This has been fixed in TDM 4.2.
To address this issue, all you need to do is set up an environment variable as shown below (assuming a default install of the TDM Portal)
CATDMWEB_APPDATA=C:\ProgramData\CA\CA Test Data Manager Portal\
If you need to know how to create an environment variable, you can refer to this document from Microsoft.
