Hello, just switched to 1.7.0, and getting the following exception when loading (which doesn't happen for 1.6.2):

Any idea why this would happen ?

Hey @pedro-leitao,

This is a known bug in 1.7.0: #4460
We're planning to publish a patch release 1.7.1 that fixes this issue sometime during this week.
