Unfortunately, we could not reproduce this issue and determine the exact reason of this issue. The error is generated by PartnerService API and, most likely, is not related to Skyvia.
We had one user with a similar error some time ago - the reason was in attachments with big HTML files. While reading these attachments via SOAP protocol the process was hanging and later failed with this error.
It is unknown what data format led to such an exception. We tested various options with our Salesforce account, but we were not able to reproduce this error. We would be grateful if you give us some details:
- whether any file was retrieved and the error occured on a specific one or whether SOAP API did not work on Attachment table under your Salesforce account at all;
- try creating several Export packages with different filter conditions in order to identify problem file(s) (e.g. filters on ContentType, BodyLength, Parent.Id, Parent.Type, etc.).
This information could help us to find solution and/or workaround for you.
Looking forward to your reply.
