PC Support Tip: "Performance Center has encountered a fatal error" while configuring LG in PC 11.50.
When trying to configure the load generator (LG) to use in a load test the following error appears:
"Performance Center has encountered a fatal error Exception of type 'System.Web.HttpException' was thrown"
After the error appears it's not possible to edit the LG related to this load test.
The problem occurs only on a migrated project from PC 9.52 where the load test was configured to use a specific LG.
The issue appears due to the fact that after the migration this specific LG was removed from the hosts list and will not appear if the host is still in the host list or if the project was saved in PC 11.50 before trying to edit it.
In order to overcome the problem, perform the following steps:
1.Edit the load test
2.Change the LG distribution to be Assign All to each group, in this example you’ll get LG1 for all groups instead of the specific host.
3.Save the load test
4.Close the edit load test window
5.Enter again to Edit load test window
6.Change the LG distribution to be Assign manually and choose the required specific host / hosts.
