Failed to get a blob from all stores on attachments export task

Issue

You are trying to export attachments but getting the error "Failed to get a blob from all stores".

Cause

As per the investigation we did (not concluded), it seems that the error happens when there is some attachment being exported that is a binary file.

Solution

We have reported this internally to the dataloader.io engineering team for a full investigation.

Alternative solution

Unfortunately, the only possible solution, for the time being, is identifying which is the file causing the error and filtering it from the export.
