Summary
ServiceNow integration v2.4.0 connects but fails keystore trust
Steps to reproduce
Integrate self-hosted Mattermost per the documentation to self-hosted ServiceNow instance > add bulk record subscription to a channel > make specified updates to the subscribed record(s)
Expected behavior
After connecting Mattermost to ServiceNow, add a subscription to a channel and receive updates from the ServiceNow bot regarding specified record updates like: state change, changes to ticket assignment, priority changes
Observed behavior
Even though the integration plugin was successfully added and connected to a ServiceNow instance, updates to the subscribed channel do not appear. Outbound HTTP logs in ServiceNow give a response of “[ERROR CODE: -1] java.security.KeyStoreException: problem accessing trust store”
This comes despite adding the Mattermost server DER certificate to the instance and validating it.
ServiceNow support will not assist since they do not publish this plugin.
