PagerDuty Object reference not set to an instance of an object.

[arielbvargas]

Don´t know if it's a configuration error, or an unexpected behaviour:

With the following PagerDutySettings.json:
/* Configuration for the PagerDuty dashboard */
{
// (Required) PagerDuty API key
"APIKey": "XXXX",
"APIBaseURL": "https://XXXX.pagerduty.com/api/v1",

/* Map of Opserver account names (usually Active Directory) to PagerDuty emails
With this provided, known users can take on-call because we know how to map the action to. */
"userNameMap": [
{
// Opserver login (probably Active Directory user name)
"opServerName": "administrator",
// PagerDuty email
"emailUser": "[email protected]"
}
]
}

OpServer is crashing:

Any help is much appreciated!

Are you seeing this on latest? The config suggests PagerDuty v1 and we upgraded to their v2 API some time ago (and updated lots of views with it).

Hi Nick! Thanks for your amazing job. I´ve updated opserver and PagerDutySettings.json. I still get:

What do you suggest in order to solve this issue?

Thanks in advance!

Hmm, check out /admin/errors where the error log details are accessible - see if we can get more info about what the API did respond with. Maybe there's a data type it's not handling here.
