Schedule refresh of a dataflow from a datalake failed (Credential is not stored)

[frenchphil]

Hi,

I try to schedule an automatic refresh of my dataflow which is conected to a datalake Storage Gen 2. When I refresh it "on demand", it works properly but the automatic refresh fail with the following error:

"Data source credentials are missing or invalid. Please update the credentials for AzureDataLakeStorage in dataflows settings page and try again"

Each time I'm going to the parameters of the dataflow, I got this message in identification information for the datasource:

I update identification information by conecting my account but it's like if my account's parameters were not stored ... 

When I put my credential, I got this (it seems to be registered): 

And about one hour after, I got: 

Can you help please ?

Hi @frenchphil 

It may because the lifetime of Azure AD passthrough token is one hour. May I know whether you have used gateway for this data source? If you configure gateway for it, will you get same issue?

Hi @v-cazheng-msft 

I don't use any gateway to access this data source. The Datalake I access to is not mine (it's administrated by a third company on Azure and they give me rights to access it) and I can't install a gateway on their architecture ...

Best regards

Hi @v-cazheng-msft 

Have you got more information about this issue ? Is it mandatory to configure a gateway to refresh a dataflow from a datalake?

I am blocked in my deployment at this point ....

Thanks for your help ... 

Best regards

Thank you @v-cazheng-msft 

I am novice in the community and I thought this part of the site was already linked with Microsoft support ...

I have a Pro Licence but it doesn't let me create a new support issue. I don't know if I have to suscribe a special "Support plan" or if I have to activate something somewhere ...
