Hello! My Import operation seemed to be working up until a certain point when it suddenly cut out stating the following:
An exception has occurred during upsert operation, the message returned from the provider is: The remote server returned an error: (400) Bad Request.
And now when attempting a new run, it quits out immediately stating the above. The first attempt managed to reacch just over 10k records, and was about 1 hour and 10 minutes into the operation. This operation is between an Amazon S3 bucket as the source, and a Salesforce organisation as the target.
Any assistance with this would be greatly appreciated!
