are you having the same issue with 2.8.0? or 3.0.0.M1?

Yes, got the same exception today at 2.8.0. At 3.0.0.M1 can't say - have'nt worked with this version yet.

Hi! Tell me please is the problem solved? I'm using 2.8.0 now.

Is there a specific test setup that reproduces the error? Even if it occurs randomly it might be good to know which setup is used to receive the Http message.

Also please consider to move forward to 3.0.0-M3 as the 2.x release train is not likely to get much attention anymore

Is 3.0 ready? I found no info at official site.

I'll try to reproduce and return with the results.

I suppose i found the problem. If .messageType is absent in the response from http-server (JSON type in this case expected), citrus peridocially recognizes message type as XML -> mismatch of types leads to failure.

But i need more iterations to prove my theory.

The problem is not with message type...

Hi. If client or server is meant by setup - i got this problem only when get messages from http-server.
