2. Check the video file size: 1554129526 / 1024 / 1024 = 1482.13 MB. See Figure 2.
3. Check the Penguin Account’s video file multipart upload. start_offset: the starting position of the chunk (counting from 0). end_offset: the ending position of the chunk. status: status, 0: disabled; 1: pending upload; 2: uploading; 3: uploading (failed); 4: uploaded. The status was found to be 3, meaning uploading (failed). It had already uploaded to the 4th chunk, 419430400 / 1024 / 1024 = 400 MB. The size of a single chunk file is 100 MB. See Figure 3.
4. The starting position of the 5th chunk is 524288,000, so the ending position of the 4th chunk is 524287999, which is correct. Check the original file in storage: /2021/10/22/1634900031.6087.46572291.mp4. The total number of chunk files is 15. There are no issues with the chunk files. See Figure 4.

5. Uploading the same video file again succeeded, and the issue did not reproduce. Below are 3 records from the transaction table. See Figure 5.

6. Summary: It seems the only next step is to have the QA team try to reproduce it later. The developers could not reproduce it. This should also be an intermittent issue. It is basically very difficult to resolve. For example, it could be due to network jitter or occasional instability of the Penguin Account servers.
