Content Range header is not calculated correctly for resumable uploader multiple requests

[cip123]

This is the output of the console.log

 LOG  bytes 0-262143/*
 LOG  upload chunk 1 {"isComplete": false, "transferredByteCount": 262144}
 LOG  bytes 262144-524287/*
 LOG  upload chunk 2 {"isComplete": false, "transferredByteCount": 524288}
 LOG  bytes 786432-1048575/*
 LOG  Big error in importing: HttpError: Invalid request.  According to the Content-Range header, the upload offset is 786432 byte(s), which exceeds already uploaded size of 524288 byte(s).!

I think the problem lies on this line:

this.__transferredByteCount += transferredByteCount

in ResumableUploader, where the transferredByteAccount is aggregating.

I corrected it to

this.__transferredByteCount = transferredByteCount

  const uploadFileInChunks = async (filePath,gdrive,name) => {
    const CHUNK_SIZE = 256 * 1024;

    try {
        // Get file size first
        const fileStats = await RNFS.stat(filePath);
        const fileSize = fileStats.size;

        // Initialize the uploader
        const uploader = await gdrive.files
            .newResumableUploader()
            .setDataType(MimeTypes.BINARY)
            .setShouldUseMultipleRequests(true)
            .setRequestBody({
                name: name || `${filePath.split('/').pop()}_${Date.now()}`,
                // Uncomment and set folder ID if needed
                // parents: ["folder_id"]
            })
            .execute();

        // Set the total content length
        uploader.setContentLength(fileSize);

        // Upload file in chunks
        let offset = 0;
        let uploadComplete = false;

        while (!uploadComplete) {
            // Read chunk from file
            const chunk = await RNFS.read(
                filePath,
                CHUNK_SIZE,
                offset,
                'base64'
            );

            if (!chunk || chunk.length === 0) break;

            // Convert base64 chunk to buffer
            const chunkBuffer = Buffer.from(chunk, 'base64');

            // Upload chunk
            console.log(`Uploading chunk at offset ${offset}`);
            const uploadResponse = await uploader.uploadChunk(chunkBuffer);
            console.log('Chunk upload response:', uploadResponse);

            // Check upload status
            const status = await uploader.requestUploadStatus();
            console.log('Upload status:', status);

            // Update offset
            offset += chunkBuffer.length;

            // Check if upload is complete
            uploadComplete = offset >= fileSize;
        }

        // Get final status
        const finalStatus = await uploader.requestUploadStatus();
        console.log('Final upload status:', finalStatus);

        // Get file metadata to retrieve ID
        const metaData = await gdrive.files.getMetadata();
        const id = metaData.files[0].id;

        return { id, status: finalStatus };

    } catch (error) {
        console.error('Error uploading file:', error);
        return {
            success: false,
            message: 'Upload failed',
            error: error.message
        };
    }

  };

Getting same error ERROR Error uploading file: [HttpError: Invalid request. According to the Content-Range header, the upload offset is 786432 byte(s), which exceeds already uploaded size of 524288 byte(s).]

Hi guys! Apologies, if I messed things up there. Currently I have no time for this project, sorry.

this.__transferredByteCount = transferredByteCount This line fixed my issue @RobinBobin Thanks @cip123
