Hello, I am seeing two errors when I sync entities between Acumaitca and BigCommerce, and was wondering if anyone had any ideas. The errors are:

Input string was not in a correct format. → Only on stock items. The last operation is Failed to Save Externally, and they are not synced to BC.

Could not find a part of the path 'c:\windows\system32\inetsrv\eusername]\users\uBC customer ID #]\companies'. → Only on customers. The last operation is Inserted Externally, and they are synced to BC. I can’t see the difference between the records that are synced and those that are not. 

I appreciate any help I’m able to get!
