rocket.chat problem with nick

[Chip13673]

I setup a bridge between Telegram, Whatsapp and Rocket.chat. There are no problems with Telegram and Whatsapp. Also there is no problem from Rocket.Chat to Telegram/Whatsapp.
But if there is a Message coming from Whatsapp or Telegram to Rocketchat there is only a error Message:

SendMessage failed: {"error":400,"errorType":"Meteor.Error","isClientSafe":true,"message":"Match failed [400]","reason":"Match failed"}

Ivestigating the error i tested some configuration changes... So it looks like there is some failure with exchanging the Nick from the other messengers to Rocket.chat. If i comment out RemoteNickFormat="[{PROTOCOL}] <{NICK}> " or set it to "", there is no problem sending the messages to Rocket.chat. But there is no nick coming with the message... so it's not very productive. Also pictures were send to rocket.chat, because there is no nick mentioned in the channel, only the picture posted by the bot-user.

matterbridge.toml

[telegram.xxx]
Token="xxxxx"
RemoteNickFormat="{NICK}: "
#MessageFormat="HTMLNick"
MediaConvertWebPToPNG=true
#MediaConvertTgs="png"
UseFirstName=true

[whatsapp.xxx]
Number="xxx"
SessionFile="xxx"
QrOnWhiteTerminal=false
RemoteNickFormat="[{PROTOCOL}] @{NICK}: "

[rocketchat.buntewelt]
Server="http://rocket.domain.tld:8008"
Login="[email protected]"
Password="xxx"
PrefixMessagesWithNick=true
RemoteNickFormat="[{PROTOCOL}] <{NICK}> "



[[gateway]]
name="somegatewayname"
enable=true
#    [[gateway.inout]]
#    account="whatsapp.xxx"
#    channel="[email protected]"

    [[gateway.inout]]
    account="telegram.xxx"
    channel="somechannelnumber"

    [[gateway.inout]]
    account="rocketchat.xxx"
    channel="#testspace"

There is also a very large error message in Rocket.chat, but i think the interesting part is the beginning of that log-message:
Exception while invoking method 'sendMessage' Error: Match error: Unknown key in field alias at format [...]

The user for matterbridge has the roles user, bot and app.
I changed it to only bot, but there was no other result.

Did i overlook something in configuration? I also tested a second, external vm to connect to rocketchat without cloudflare tunnel. There are the exact same errors...
Maybe someone cloud help me out?
Thanks...
