[Maplemx]

"Event loop is closed" is a tricky issue we're still looking into it in main development framework.

Most of time, this error report is just annoying but will not affect the final output.

To follow up this bug fix, check this issue: Maplemx/Agently#65

[Maplemx]

We seems like having fixed this issue in Agently v3.2.2.10

Please update Agently by using pip install Agently>=3.2.2.10 to solve this problem
