Import recurring calendar items fails

BennieWoef

Hi,

I'm testing Grommunia as a replacement for Kopano. We only have 4 account, so I want to migrate mail and calendar in a manual way. Migrating mail is no problem via IMAP.
I have an export (.ics) of my calendar and try to import it in Grommunio. Via the web interface it simply says error.
Via Thunderbird and caldav importing it results in error 500.
If I connect via TBSync in Thunderbird, i can import the Calendar in Thunderbird but synchronizing goes stuck.
The log file shows next message:

9/08/2025 08:42:24 [ 1641] [FATAL] [ben@nieuwhof.eu] Fatal error: /usr/share/php-mapi/class.recurrence.php:198 - Uncaught TypeError: array_push(): Argument #1 ($array) must be of type array, null given in /usr/share/php-mapi/class.recurrence.php:198 Stack trace: #0 /usr/share/php-mapi/class.recurrence.php(198): array_push() #1 /usr/share/grommunio-sync/lib/grommunio/mapiprovider.php(1659): Recurrence->createException() #2 /usr/share/grommunio-sync/lib/grommunio/mapiprovider.php(1261): MAPIProvider->setAppointment() #3 /usr/share/grommunio-sync/lib/grommunio/importer.php(415): MAPIProvider->SetMessage() #4 /usr/share/grommunio-sync/lib/request/sync.php(1589): ImportChangesICS->ImportMessageChange() #5 /usr/share/grommunio-sync/lib/request/sync.php(565): Sync->importMessage() #6 /usr/share/grommunio-sync/lib/request/requestprocessor.php(94): Sync->Handle() #7 /usr/share/grommunio-sync/index.php(114): RequestProcessor::HandleRequest() #8 {main} thrown (1)
Can anybody give me hand on how to resolve this?

Thank you in advance.

Why you don not use the import script https://github.com/grommunio/gromox/blob/prime/tools/kopano2grommunio.sh ?

Hi,

Thank you for your reaction. That's how I started. However I don't get the python script kbd-uidextract not executed because it fails on user SYSTEM in Kopano.
It says:
[ [error ] HrLogon server "https://nhfserv:237/kopano" user "SYSTEM": logon failed d {}]
So I don't know how /tmp/kdb-uidextract.map should look like'. Ik I only put an account and store UID in it, kopano2grummio.sh says:

18.08.2025 18:26:34 WARN Migration of mailbox me@example.com with Kopano GUID 008CE5A6D2974AA094E5D796801B3766 start ^[[1;31m^[[1;31mCould not open (null) for writing: Bad address. Using stderr.Could not open (null) for writing: Bad address. Using stderr.^[[0m ^[[0m kdb2mt: ACLs will be extracted and converted. /tmp/kdb-uidextract.map: parse error 18.08.2025 18:26:34 INFO Mailbox: me@example.conm migrated successfully 18.08.2025 18:26:34 WARN Migration of mailbox me@example.com end

However nothing is written in the Grommunio store.

Again, thanks for Help.

Looks like https is not activated on the kopano server. Try the kdb-uidextract-limited file instead.

Hi Walter,

How simple could this be. This was the solution. Email, Calendar, Tasks, Notes and Contact migrate perfectly.
Thank you for the advice.

Glad to hear it's working.

Now I'm looking for a way to change the state of this issue as solved.
