DataFlowManagerClient.getPayload: 400

Question

My data flow was working fine for months and it failed last night. I found the source of the problem and I'm debugging manually. Same error. What is happening?

java.lang.Exception: DataFlowManagerClient.getPayload: 400 - RunId: 62d84de6-e35b-4666-834e-3dbfc7050a86

Hi @Carlos Parra ,

Thankyou for using Microsoft Q&A platform.
Looks like the issue is credential is invalid. Can you please test if the connections for all of the linked services used in the data flow are successful.
There are several potential reasons which could cause this:

1. Configured a Git repo for the factory and used the repo for multiple factories
2. The factory has been moved to different resource group/subscription
3. Created the linked service in different git branches then merged them together in master branch.

In case everything looks good from your side, I would suggest to try debugging again after few hours and update accordingly so that we can reach out to our internal product team to investigate further.

Hope this will help. Please let us know if any further queries.

Answer 2

I was able to deduce what the problem was. This has to do with running a pipeline when azure vault is used and the pipeline is run from a branch. You guys need to test this scenario and document it. There is nothing wrong, all this is, again, is when a process is run from a branch and the branch cannot communicate with the key vault that is in production...something of that nature. Please document this. Thanks.
