[Raven 4.0] Exception while storing

[Anders Strömberg]

Hi,

I'm currently loading documents from a 2.5 database, transforming them to a new format and storing them in a 4.0 database (this is all done in C# code, the smuggler is not used).

The client side is 4.0.0-rc-40025 and the server is 4.0.0-nightly-20171218-0502 at some random interval I get the following error:

System.AggregateException: One or more errors occurred. ---> System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

The error is randomly occurring so I cannot reproduce this for a specific document. Does anyone have a clue what might cause this?

This looks like a client side failure in serialization, is it possible you have a string value that is greater than 32KB?
