"Payload too large" while upgrading "OutSystems Sample Data"
Question

Hi, 

We are facing a problem while upgrading "OutSystems Sample Data", it shows below error 

Attached the logs in  "Error stack.txt", the exception I can see is:

System.ServiceModel.ProtocolException: The remote server returned an unexpected response: (413) Request Entity Too Large. ---> System.Net.WebException: The remote server returned an error: (413) Request Entity Too Large.

If download the .oap and upload from the service center, it shows "Payload too large"

The .oap file is about 38Mb, and I checked the configuration, all are for large factory


Anyone can advise how to solve it?

Hi,

I suggest you to update development environment and try  i.e. Service studio

We tried both Service Studio and Service Center, and both failed

Hi, 

This plugin mostly insert sample data to your environment, this is not mandatory (except if you want to preview the sample application)

Also if this personal environment ?

The reason we upgrade it is because it's a dependency of screen templates provided by OutSystems. It's in our on-premise environment. 

We managed to upgrade it in the app server by accessing the service center by https://<<server name>>/ServiceCenter, but we still don't have any clue of the issue.
