Missing error logs

[gusmith]

In the motor quote activity v0.6.7 which is using the sdk v2.0.0, the activity does not return any logs when an error occur. What we observed in https://github.com/ambiata/iag-motor-quote/issues/30 was that when running a exclusion rule, and an error occur in the exclusion (in the case it should have been a type error raised), there are nothing logged in the container.

The only thing we can observe is that in atmosphereX, we got such log:

@gusmith I don't understand the issue so I can't propose a solution to fix it.

The configuration on iag/stage and iag/prod pointed to the iag/test custom activity.

@gusmith I let you close the PR.
