Connection to Google Drive fails after first use

GiantIguana · 11-28-2021, 10:10 AM

Hi,
I'm using cloud connect of Calibre Companion to connect with my Google Drive account. I could connect, retrieve my Calibre database, and download books. But then after I quit the app, wait about an hour, then opened the app and tried connecting again, I got the error message below.

"Cloud provider internal error
CC is unable to communicate with the cloud provider. The cloud
connection will close. On the next connect you will be required to
re-authenticate with the provider. (Attempt to invoke virtual method
java.util.List com.multipie.cclibrary.Cloud.Google.Children.getlt ems()'
on a null object reference)"

The only way I could connect again was to "Reset cloud connection" and added and authenticated my Google Drive on Calibre Companion again. After I re-added and re-authenticated my Google Drive, the app would be able to connect to Google Drive, but then if quit the app, the same problem happened again.

Does anyone have this problem or have any suggestion how to fix this? Thank you.

Google Drive is not compatible with Calibre or Calibre Companion, because Drive changes the Calibre identifier to its own unique identifier.
