TbSync + CalDAV doesn't work in Thunderbird 2022 ESR beta

Your environment

TbSync version: 3.0.1 DAV-4-TbSync version: 2.0.2 Thunderbird version: 100.0b3 (64-bit)

Expected behavior

A TbSync + DAV-4-TbSync setup which previously worked on v91 will continue to work on the next Thunderbird ESR (likely v102).

Actual behavior

The Thunderbird footer lists “TbSync Error”, and clicking it brings up the TbSync account manager screen, which has the following error: “The account requires the DAV synchronization provider, which is not currently installed”.

However, the DAV synch provider is installed:

Steps to reproduce

• Set up a TbSync + DAV account on Thunderbird v91.
• Upgrade to Thunderbird beta (v100b3 in this case)
• Note the TbSync status in the TbSync account manager screen

Additionally, I see the following error in the debug log, which looks pretty suspicious!

** Tue Apr 26 2022 09:24:44 GMT-0400 (Eastern Daylight Time) **
[Check4Lightning] : Error during lightning module import: TypeError: TbSync.lightning.cal.getCalendarManager is not a function

There is no version for TB91+ yet. I am surprised you were able to install them in Beta.

I will work on an update for the next ESR in a couple of weeks.

I do not know. Try the native CardDAV support in TB 102
