Indicates that the api tried to construct a
Guc (Globally Unique Code) e.g.
designs_myCustomDesign and it does not have a valid local name.
Guc is made of 3 parts
<feature>_<local name>_<unique id>, the first 2 being required. When a
Guc is created from data you have entered, if the property used to generate the code does not include alpha numeric characters from
0-9A-Za-z then it will fail to generate a local name.
Make sure you use an alpha numeric character from
0-9A-Za-z if you are providing information to the API directly or via a client. Spaces and characters outside of this range will be cleaned when generating a code.
This is commonly seen with
Name form fields on the web or mobile clients.
