Create block blob (V2) - errors



I am trying to create a flow that will archive note attachments from Dynamics 365 CE to an Azure Blob. The error I am receiving is on the Create block blob (V2) action.


The Error Details read: "The response is not in a JSON format".


However, the message in the output reads: "AuthorizatrionPermissionMismatch | This request is not authorized to perform this operation using this permission"


So I am assuming that the problem is that the flow does not have permissions to write to this blob.


I can't seem to find information on how to configure the Storage Account to allow D365CE to write to a blob.


Any guidance is greatly appreciated

You can try to check this information here:  Assign an Azure role for access to blob data and see if it helps.


If it doesn't help, also try this:





Also check if Azure AD Integrated does not work in the Power Automate Action under Authentication Type then go ahead and try to change Authentication Type  to Access Key - here is also how to set up and manage storage account access keys in Azure as well for reference.
