Empty Metadata fields in new model throw exception #8

Open nunopimpaomartins opened 3 years ago

nunopimpaomartins commented 3 years ago

When editing the Metadata information of a new trained model, if the Description and Authors fields are left empty, it will throw the following error into the console (see below).

It only happens in a new trained model. If the same thing is done in a model that already had metadata in it, no error is shown.

[ERROR] Module threw exception
