ContainerName: %containerName;, path: %path;." - **Cause**: A problem with the Blob Storage operation. - **Recommendation**: To check the error details, see [Blob Storage error codes](/rest/api/storageservices/blob-service-error-codes). For further help, contact the Blob Storage team. ## Invalid property during copy activity - **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. ## Error code: FIPSModeIsNotSupport - **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. ## Error code: AzureBlobInvalidBlockSize - **Message**: `Block size should between %minSize; MB and 100 MB.` - **Cause**: The block size is over the blob limitation. ## Error code: AzureStorageOperationFailedConcurrentWrite - **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. ## Error code: AzureAppendBlobConcurrentWriteConflict - **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. ## Error code: AzureBlobFailedToCreateContainer - **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](security-and-access-control-troubleshoot-guide.md#connection-error-in-public-endpoint). ## Related content For more troubleshooting help, try these resources: - [Connector troubleshooting guide](connector-troubleshoot-guide.md) - [Data Factory blog](https://techcommunity.microsoft.com/t5/azure-data-factory-blog/bg-p/AzureDataFactoryBlog) - [Data Factory feature requests](/answers/topics/azure-data-factory.html) - [Azure videos](/shows/data-exposed/?products=azure&terms=data-factory) - [Microsoft Q&A page](/answers/topics/azure-data-factory.html) - [Stack Overflow forum for Data Factory](https://stackoverflow.com/questions/tagged/azure-data-factory) - [X information about Data Factory](https://x.com/hashtag/DataFactory)
