For events that cannot be decrypted, event.decrypted() will be false, event.type() will be m.room.message, and event.content().get().at("msgtype") can have the following values:

xyz.tusooa.kazv.not.yet.decrypted

This means we haven't even tried to decrypt this event. The most probable case is that we do not have the corresponding session key.

moe.kazv.mxc.cannot.decrypt

This means that the corresponding session is known, but there are errors in the decryption.

The event content will have the following properties:

• moe.kazv.mxc.errcode The error code.
• moe.kazv.mxc.error The error message.
• moe.kazv.mxc.raw The raw data associated with the error.

Possible error codes
