Timeout Error When Uploading Large Files to Azure OpenAI Assistant Service

Question

Hi,
I'm encountering a timeout error when trying to upload large files 260 MB (up to 512MB) to the Azure OpenAI service using the assistantsClient.uploadFile method. I understand that can upload 512MB 20 files. The error occurs after the upload begins, and the operation fails with the following message:

try {

          const fileUploadPromises = files.map(async (file) => {
            // Read the content from the uploaded file in binary mode
            const fileContent = await fs.promises.readFile(file.path);
            // Define the filename for the upload
            const filename = Buffer.from(file.originalname, 'latin1').toString('utf8');
            console.log("before file upload to assistant..");
            // Upload the binary file content using Assistants SDK
            const uploadAssistantFile = await assistantsClient.uploadFile(fileContent, "assistants", { filename });
            console.log("after upload file to assistant..");

            return { fileId: uploadAssistantFile.id, filename: filename };
        });

          // Wait for all file uploads to complete
          const fileIdsWithNames = await Promise.all(fileUploadPromises);

          // Extract fileIds and filenames separately
          const fileIds = fileIdsWithNames.map(file => file.fileId);
          const filenames = fileIdsWithNames.reduce((acc, file) => {
              acc[file.fileId] = file.filename;
              return acc;
          }, {});

         
          // Create an assistant using Assistants SDK
          const assistantResponse = await assistantsClient.createAssistant({
              model: model,
              name: name,
              instructions: instructions,
              tools: [{ type: "code_interpreter" }],
              fileIds: fileIds,
          });

          console.log("Assistant created:", assistantResponse);

  },

}

I'm looking for guidance on:

1. Whether there is a specific timeout limit imposed by the Azure OpenAI service for file uploads.
2. Best practices for handling large file uploads to avoid timeouts.
3. Any server-side configurations or SDK options that can help mitigate this issue.

Any advice or insights would be greatly appreciated!
