Forwarding Messages on encrypted channels doesn't work

[SGSSGene]

Hi, I have setup pantalaimon in combination with matrix-poll-bot. This works for unencrypted channels without issue. But on enrcypted channels forwarding from pantalaimon to matrix-poll-bot gets stuck. Pantalaimon shows the message:

[2020-08-21 10:37:46.009047] WARNING: pantalaimon: Encrypted event is not a megolm event:
{'event_id': '$MjDQK5jg_UTWY5XKIYapIfnto_MeLsdY-bk0KG5rZ98',
 'sender': '@me:myserver.org',
 'type': 'm.room.encrypted'}

The message from @me:myserver.org was send by element desktop app, I also tried element android app, but same result. Any clue of what I am doing wrong?

What does forwarding here exactly mean? How does a forwarded event look like?

In have the same problem. Forwarding in this case means:

• @ me and @ pollbot are in one matrix room
• @pollbot is logged in with the "device" matrix-poll-bot (in a docker container) via pantalaimon (in another docker) in order to handle encyption
• @ me is logged in with "element" app
• @ me is posting a message (e.g. a poll-request starting with "!poll ...")
• expected behavior: message is decrypted by pantalaimon and forwarded to "device" matrix-poll-bot; matrix-poll-bot answers the message (e.g. by setting up a poll)
• actual behavior: message seems not to be decrypted by pantalaimon (see WARNING in post from @SGSSGene); matrix-poll-bot shows no reaction

Further information:

• matrix-pol-bot reacts on resp. accepts invitation to the matrix room, however I also see a similar error from pantalaimon
• matrix-pol-bot reacts right in unencrypted rooms; pantalaion's log INFO: pantalaimon: Room <xxx> is not encrypted skipping...

EDIT: In the end for me the solution was quite simple... RTFM :sunglasses:

Add/Modify the following line in config.yaml of the matrix-poll-bot: skip_filter: true
