Eventstore UnknownError: Could not recognize BadRequest

I'm currently using Eventstore, and I'm receiving the following error: Could not recognize BadRequest;

from:

game process tick failed UnknownError: Could not recognize BadRequest
    at unpackToCommandError (\node_modules\@eventstore\db-client\dist\streams\appendToStream\unpackError.js:53:12)
    at ClientDuplexStreamImpl.<anonymous> (\node_modules\@eventstore\db-client\dist\streams\appendToStream\batchAppend.js:38:66)

For some reason, it seems like it is something with my handler:

async function   gameProcessPush(channel,event) {
    console.log("pushing:",event);
    try {
        console.log("trying to append..:",event);

           await client.appendToStream("factory",[event]);
           console.log("appending to stream");
        } catch(e) {
            console.log("game process tick failed",e);
            throw  {live: false, code: 26, event: event}
        }
        console.log("game processing...");

}

What am I doing wrong here?

rest of debug code:

processing factory failed {
  live: false,
  code: 26,
  event: { type: 'factory-creation', sub: 'sub-factory', userid: 1 }
}
result in :  undefined
