Hello,
Welcome to this forum.
The error seems not common. I am not sure what parameter value is not correct, but generally binarySeq, filekey, versionCode these parameters make errors. Can you check this blog?
Hopefully you have read this document Content Publish API Reference | Samsung Developers, if you miss this. For binarySeq parameter “Copy the value from the contentInfo response. This value is not visible in Seller Portal.”
Please let me know your update.
