This article provides suggestions to troubleshoot common problems with the Azure Blob Storage connector in Azure Data Factory and Azure Synapse.
-
Message: "Blob operation Failed. ContainerName: %containerName;, path: %path;."
-
Cause: A problem with the Blob Storage operation.
-
Recommendation: To check the error details, see Blob Storage error codes. For further help, contact the Blob Storage team.
-
Message:
Copy activity \<Activity Name> has an invalid "source" property. The source type is not compatible with the dataset \<Dataset Name> and its linked service \<Linked Service Name>. Please verify your input against.
-
Cause: The type defined in the dataset is inconsistent with the source or sink type that's defined in the copy activity.
-
Resolution: Edit the dataset or pipeline JSON definition to make the types consistent, and then rerun the deployment.
-
Message:
Fail to read data form Azure Blob Storage for Azure Blob connector needs MD5 algorithm which can't co-work with FIPS mode. Please change diawp.exe.config in self-hosted integration runtime install directory to disable FIPS policy following https://learn.microsoft.com/dotnet/framework/configure-apps/file-schema/runtime/enforcefipspolicy-element.
-
Cause: Then FIPS policy is enabled on the VM where the self-hosted integration runtime was installed.
-
Recommendation: Disable the FIPS mode on the VM where the self-hosted integration runtime was installed. Windows doesn't recommend the FIPS mode.
-
Message:
Block size should between %minSize; MB and 100 MB.
-
Cause: The block size is over the blob limitation.
-
Message:
Error occurred when trying to upload a file. It's possible because you have multiple concurrent copy activities runs writing to the same file '%name;'. Check your ADF configuration.
-
Cause: You have multiple concurrent copy activity runs or applications writing to the same file.
-
Message:
Detected concurrent write to the same append blob file, it's possible because you have multiple concurrent copy activities runs or applications writing to the same file '%name;'. Please check your ADF configuration and retry.
-
Cause: Multiple concurrent writing requests occur, which causes conflicts on file content.
-
Message:
Unable to create Azure Blob container. Endpoint: '%endpoint;', Container Name: '%containerName;'.
-
Cause: This error happens when copying data with Azure Blob Storage account public access.
-
Recommendation: For more information about connection errors in the public endpoint, see Connection error in public endpoint.
