EDR Interface object __repr__ function sometimes fails

[stevehadd]

While testing the EDRInterface class, I tried creating one in a noteboo and got an error from inside the __repr__ function, because it was trying to display the number of collections, but self.collections was None.

to do this, I just had a blank notebook, imported edr_explorer.interface, then created a EDRInterface() object.

OK, this was actually just my mistake. I had a typo in the server URL. You might like nonetheless to have a more graceful fail ion this case, maybe have the repr print an error message about server not existing.

Good find 👍
