How to solve Internal Server Issue

I am using the IIS for Rhino compute server and have one endpoint which calling the c# code for creating some lattice structure .Earlier got error of 100 sec timeout then after adding the Rhino_Compute_Timeout in environment variable that issue is resolved.Then getting error as Internal server error

Can someone help me with this?

Thanks in advance.

To me, this looks like it’s a bug somewhere in the endpoint you’re using to create the lattice structure. Are you able to debug this endpoint and make sure it’s working as you expected?
