Hi guys
I’m getting a repeated error when trying to upload datasets to Pix4D Cloud. This is from Matic.
The error in the log is:
[2026-08-05 20:37:16][02%CPU][33%RAM]Upload images Unable to parse ExceptionName: BadDigest Message: The CRC64NVME you specified did not match the calculated checksum.
I get maybe 8-20% through any dataset and it fails. Same happens randomly when uploading other parts of the dataset (Ortho etc), but further attempts sometimes succeed.
This is a little frustrating, so any tips would be a great help.
Many thanks
Hello,
I’m a developer at Pix4D, currently investigating this issue.
I expect the issue to be fixed in the next PIX4Dmatic stable (2.10).
Cheers,
Yvan
Hi Yvan - thanks very much for the quick response. I’m guessing that there is nothing I can do my side in the meantime?
Also, when do you think the update will be available? I currently cannot deliver outputs to my clients which is impacting our business.
Thanks again

Hello Kerry,
The problem is apparently caused by a bug in this library:
https://github.com/aws/aws-sdk-cpp/discussions/3787
We have a tentative fix that is currently being tested by the QA team.
In the mean time the only workaround I would recommend is to upload only one asset at a time in the PIX4Dcloud > Upload dialog. The reason being that the upload sequence currently aborts whenever any error happen. By uploading only one asset at a time you should reduce the chance for failure compared to a full upload, although of course this is more cumbersome.
Also probably: use a stable and fast network connection, e.g. no bad wifi. And don’t do any other intense network activity during the upload, this should avoid upload retries which increase the probability for a failure.
Sorry for the trouble.
Best regards,
Yvan
Hi Yvan
Thanks for the update. I appreciate that this is not a problem that you have caused, but I feel that the response from Pix4D has not been enough. The only way that I am able to process and share results with clients is to launch an EC2 Instance, install Matic and then process on that instance. The data upload from the EC2 instance to your cloud takes a few seconds and therefore has not (yet) failed.
That being said - I have had to do this for almost 2 months now and at a cost a a couple thousand dollars. We did this because we had a whole bunch of deliverables from a large project to get onto your cloud platform.
I feel that I need to escalate this to a regional commercial leader - we desperately need to see this fixed. I really do not want to move to a different platform but if the end to end process is not fixed then we may have no choice.
Do you have a timescale for a fix please? Days, 1 week, 1 month?
Kind Regards
Kerry
Hello Kerry,
Sorry for the late reply, I was out of office.
The fix was validated, it will be incorporated in PIX4Dmatic 2.10 (stable) that will be released targeting August 24.
Sorry for the inconvenience.
Best regards,
Yvan
Hello @perytonsurveys , the new PIX4Dmatic 2.10 (stable) was released today, in case you want to give it a try. Thanks!
