Hi @mohamedalthaf, I see that you are trying to use the terminal activities together with rumba (from the name of the other workflow you have opened). So I assume you are trying to use the EHLLAPI provider.
For the EHLLAPI provider to work, Rumba needs to be started and connected to the host system before the connection is attempted. Can you confirm that is the case?
Also can you tell me version of the terminal activities and the Rumba version?

Hi @bogdan.gaspar . Thanks for the reply.

My UiPath Terminal activities packger version is 2.8.2
Rumba version 10.2 HF

Before connecting using terminal session activities, I used start process but still I get the following error

The HLLAPI configuration in the terminal session looks correct.
Make sure you have you enabled “Classic HLLAPI data structure” in Rumba (Menu Options → API).

Then start rumba manually and connect to the mainframe. Once you see the screen click on the “Start Recorder” button to test the connection at design time.

The “start process” activity will only work at runtime and even then you would have to wait and make use Rumba was properly loaded (use a Delay activity or a Check App State activity).

Hi @bogdan.gaspar. After a long gap I restarted to work on this and again I got the same error and I finally came to know that in addition to the checklist you mentioned I need to select the session short name. In Rumba > API > Identification > Select session short name > Apply > Ok

Now I can able to connect without any issues.

Sharing this so it will be helpful for other developers
