`aerich migrate` fails with version `0.6.3`

Hi, I'm having issues when running aerich migrate using version 0.6.3. However, when downgrading to 0.6.2 the commands works properly.

Here is the complete traceback:

Check your connection, I tried but is right

Hi @long2ice, I just tried again and the problem persists. I'm running PostgreSQL locally and it goes well with 0.6.2 but not with 0.6.3. What kind of extra info can I provide? Thanks for your help
