Error when sending email from Salesforce when PagerDuty is enabled

When “Enable PagerDuty triggers on Case Creation and Case Comment” is checked, we get the following error trying to send an email from a case in Salesforce.

We can’t save this record because the “Email Auto Update Provided To Customer” process failed. Give your Salesforce admin these details. This error occurred when the flow tried to update records: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY: pagerdutyinc.PagerDutyTrigger: System.LimitException: pagerdutyinc:Too many SOQL queries: 101. You can look up ExceptionCode values in the SOAP API Developer Guide. Error ID: 2062552124-135757 (1229928336)k up ExceptionCode values in the SOAP API Developer Guide. Error ID: 2062552124-135757 (1229928336)

Can you help determine what is causing this error?
