This article provides suggestions to troubleshoot common problems with the Azure Blob Storage connector in Azure Data Factory and Azure Synapse.
Error code: AzureBlobOperationFailed
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.
Invalid property during copy activity
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.
Error code: FIPSModeIsNotSupport
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.
Error code: AzureBlobInvalidBlockSize
Block size should between %minSize; MB and 100 MB.
Cause: The block size is over the blob limitation.
Error code: AzureStorageOperationFailedConcurrentWrite
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.
Error code: AzureAppendBlobConcurrentWriteConflict
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.
Error code: AzureBlobFailedToCreateContainer
