问题
We have implemented an SSIS package which downloads the file from Azure blob storage. The package works when we execute from local development box. But it's failing on TEST environment.
This was working earlier both local and TEST environment. We couldn't figure out what went wrong recently.
Can somebody help us here?
Following are the software components we have installed.
SQL Server Version: 2016 SSDT : Microsoft SQL Server Data Tool Visual Studio 2017 Service Feature Pack: SQL Server 2016 Integration Services Feature Pack for Azure (x64) Management Studio: Microsoft SQL Server Management Studio - 17.9
Following are the properties we have setup.
Component: Azure Blob Download Task. Properties: AzureStorageConnection. LocalDirectory: BlobContainer: FileName
Following are the error message we are seeing in the execution context.
Azure Blob Download Task:Error: There were errors during task validation.
Azure Blob Download Task:Error: The task has failed to load. The contact information for this task is "".
Azure Blob Upload Task:Error: Failed to load task "Azure Blob Upload Task", type "". The contact information for this task is "".

For the first error, please refer to Maintenance Plan Error https://blog.sqlauthority.com/2018/02/16/sql-server-maintenance-plan-error-cannot-create-task-xml-task-eue-error-0x80070057-parameter-incorrect-onpreexecute/ Error: The task with the name "Data Flow Task" https://social.msdn.microsoft.com/Forums/ie/en-US/0b57adfa-0872-4cd4-85d8-40bfaa520285/error-when-executing-ssis-package?forum=sqlintegrationservices
Just for clarification : Have you could try following options: 1. Try using DTexce tool to execute the package to check if this issue persist. 2. Register the Azure Blob Task into GAC manually. 3. Check if the account has permission to upload file to Azure.
