Dataflows - refresh gives error about AzureStorage.BlobContents matches no exports

I have the same problem, i am trying to pull a table from my onpremise server to a dataflow , i can save it but when i try to refresh i get this error

Error: The import AzureStorage.BlobContents matches no exports. Did you miss a module reference? R

i know my data getaway works as i have several dataset already pulling this table from the same db server.

any idea

******* Update 15-11-2018 ************

I think, i found my problem and its working now.

i want to provide my environment and case so people can check if they have the same scenario.

1) i have enterprise data gateway installed and working for my power bi tenant, no problem here

2) i  normally use a service account (Window Account) as credential to access my on Premise Data Sources

 now, that service account does not have office 365 setup and power bi access, i use my personal account to create data source in the gateway but i use that service account to access my databases.

when i created the dataflow, it seems the gateway find the data source already created in my gateway but also use the credential infomation so i dont pass new credential.

i dont know how the internals of this process work but i guess the daflow use somehow those credential to do something and it fail,( i dont think the error i am getting , describe well the problem),

WorkAround, i have another data gateway and that one dont have the data source created so the dataflow process ask me for credential , when i use my personal credential that have oficce365 and power bi access correctly, it work without problem

hope this can help somebody else
