[leibale]

it's return ApiError to callback

Invalid JSON payload received. Unknown name "max_in_progress": Cannot find field.

Where is that field hiding? I'll find it unless @callmehiphop beats me to it.

I wasn't able to reproduce this locally - @leibale would you mind sharing some example code to help reproduce this error? I believe maxInProgress is a convenience option for the client only, so I'm a little confused on how it's getting sent to the upstream API.

[leibale]

when you create a subscription you can set the interval and stuff like this, but you can't set the maximum of messages your worker will work in parallel.
at version 24 (I think) wee (I create a pull request) add option to set the
maxInProgress and the subscription not pull more messages if your worker not call to message.ack or message.skip (this functions do -- to the counter and check if there is more messages).

I'm sorry for the English..
