AttributeError: 'NoneType' object has no attribute 'send'

[during-code]

Hello, may I ask the result of my connection calling connection.is_healthy() is TRUE, but why does the query or insert operation get an error AttributeError: 'NoneType' object has no attribute 'send'

Can you supply an example that demonstrates the problem? You should not get that error to begin with, and if you do, you should see is_healthy() return `False.
