Hello guys,
while upgrading from 17.0.1.10.1 to 18.0.10.2 the following error message occured.

For context:
Occured error: "InvalidArgumentException: Column name \"iqmUw_flow_operations\".\"entity\" is NotNull, but has empty string or null as default."

It happens here:
https://github.com/nextcloud/server/blob/35be4fdb019da658a824f41dc4bf0f415c032cb8/lib/private/DB/MigrationService.php#

On a fresh install of the snap, the root.ini file is not created from the first run of start_mysql. Consequently, mysql-client fails to run as well. Has this issue been seen before?

Currently, Airshare doesn't have an added layer of security over the code. Adding a password feature would allow for an extra layer of security, especially when sending more sensitive information.

Describe the bug
After the user drag and drop the file in Twake, he needs to put the mouse into the textbox message then press enter keyboard to send the file

Expected behavior
After drag and drop the file into twake, the user is able to press enter keyboard to send the file immediately, no need to put the mouse into the textbox
