Premium Dataflow Blocks Error

[Anonymous]

Hi, 

I am trying to query data from Snowflake to Power BI by using the Dataflow connector and a premium license, but I am getting this error: 

Error: Data Source Error : DataSource.Error: AzureBlobs failed to get contents from 'https://wabieus2bpcdsa.blob.core.windows.net/558902bf-70c6-4e9b-989f-296cfd413ecb/Journals%20Clicks%...'. DataSourceKind = AzureBlobs DataSourcePath = https://wabieus2bpcdsa.blob.core.windows.net/558902bf-70c6-4e9b-989f-296cfd413ecb/Journals%20Clicks%...

Any ideas on how to solve it? or change the size of those blocks in the query so that I can query the data? Does this mean that is too much data for Azure to manage? and the only way for me to manage it would be to reduce the scope of my query? 

Any help related to this topic is appreciated since I have not used azure blocks.

Hi @Anonymous ,

According to your error link, I think the error code corresponds to

 

The other error codes are listed here:

Blob service error codes (REST API) - Azure Storage | Microsoft Docs

You need to fix the error, by reducing uploaded block blob size.

Additionally, you can check whether all configurations are correct according to this artical:
