Can't start the deployment A problem occurred while validating the content for deployment.

[Cws27]

I have been usign deployment pipelines for about a month with our company's premium service. I have the dimond in all three WKSs (dev test prod) and I had not had any issues deploying until yesterday after publishing some updates to my data set. I starting getting a message that the deployment would not start. I have tried publishing an earlier version, refreshing in desktop before publishing and it has not worked. I had been using 2 data flows from workspaces in the deployment pipeline and I even moved them to a seperate workspace in the same capacity. I can deploy new reports but not the dataset. I have researched hte docs but there is not a lot on this. Can someone please help me figure out the cause of this.

Hi @Cws27 

if there are no additional errors, and it is all in a Premium App Workspace, I would then log a support ticket.
