Issues with data imports through the WCF API on the EU and US instance

Incident Report for Viedoc

Postmortem

Description

After release of Viedoc 4.80, the WCF API did not accept requests with a large amount of data.

This was for example causing the import of clinical data through the WCF API to fail.

Cause

When migrating the WCF service to dot NET core, the maximum size of message accepted was set to default (65535 bytes) in the framework.

Corrective action

Updated the code to change the message size to a configurable value. And changed the configurable value to accommodate large messages.

‌

Preventive action

The message size is set to max value that can be handled by system.
