Failing GoodData Writer uploads

After last GoodData maintenance some uploads to GoodData using our writer are started failing with the following error:

Running the LoadData task again manually will be successful. If you're running more tasks in one job, you can disable the failing job to get all the other tasks through. We have discussed the error with GoodData support and this is what they have to say:

I have already confirmed by our R&D engineers, that we have introduced the issue during the R119. We have prepared the fix for the issue and the internal discussion about the fix delivery has already been triggered. The fix unfortunately requires short time (up to 10 minutes) GoodData upload subsystems outage, therefore the our responsible managers are trying to find the best window for its delivery.

I can also confirm, that temporal switching OFF of the gZip in the command would serve as workaround, but I do as well understand the concerns you are mentioning that keeping you away of using it.

I'll share further information w/ you as soon as I have them available.

Currently we cannot turn off gzipped transfers for all projects as it will slow down all uploads. Let's wait if GoodData can release the fix during the weekend and if not, we'll implement temporary gzip disabling for affected projects early next week. Please bear with us, feel free to drop us a line at support@keboola.com if you're concerned about your project.

UPDATE 4:08pm CEST: GoodData announced maintenance for August 20th 2016. During this maintenance this bug should be resolved.

UPDATE Monday August 22 7:30am CEST: We're still rarely experiencing this issue.

UPDATE Monday August 22 2:40pm CEST: We have deployed a workaround fix for the bug so GoodData data loads now should work as expected.

We're sorry for this inconvenience.
