Unable to load headers from the XLSX data source after Utah upgrade

[Piyush Shewale1]

Hello all,

I'm testing development instance after cloning dev instance and upgrading it to Utah release and found that for one particular catalog item, we were using data sources with xlsx file attachment. These attachment files were not cloned, so I had to import xml from production to development instance. After that, when I tried to load records on data source, it's giving me this error - 

This attachment file is same as from production instance, where its being executed without error.

Can someone help me figure out what might be cause for this issue? Thanks.

Hi, you state that you imported attachments via xml, if you imported xml of sys_attachment records, did you also import the related sys_attachment_doc records?

When a file is saved to an instance it is broken into chunks and these are stored on sys_attachment_doc table, with the sys_attachment record being a parent\container.
