Hello I make a database for a project which has foreign keys, when executing an insert I always get these messages but if the insertion of the elements is made without any problem but I would like to know if it can cause problems for me error that appears to me.
If you are doing insertion using the insert() method, this does not cause an error, you simply get -1 when the insertion of data was not done for some reason.
This specific error
Failed to do file read, got: 0, amt: 4096, last Errno: 2
It can happen when you perform some operation in a table which has an incorrect structure, uninstall the application and try again.
