Internal Error in Create Service

[pasargad]

Hi,

I'm using WHMCS 8.0.4

It was working very good and no problem.

But, I don't know why from last day I can't create host and it have problem and show: "Internal Error (ID 490172067730786)"

All work that I did:

1- I check my API Token. It's working and connected.

2- Active Log and debug in setup. Not show any error or warning to me.

3- check error_log file in host. but not any error or warning to me.

Thank you

Now, I check the system activity log and show this error:

Application Link Provisioning returned the following warnings: API failure: You do not have a user named “freights”. XIDs: 3kfcdj, zs5ke7, p6b69a, uakkvr, j43fb9 and 10 more., API failure: Provide the “app” parameter for the “Whostmgr::API::1::Integration::create_integration_link” function. XIDs: vhgew2

I don't know what is the problem.

thank you
