Unable to obtain master key (SQL Request)

[shaneoss]

Sorry this question isn't really for Getting Started Forum, but there was no Nintex for SharePoint. Only Nintex for Office 365.

Anyone seen this error before? For a SQL Request action on a Nintex Form (classic) when testing I get...

Test Result

Unable to obtain master key.

Guessing Master key to access Secure Store Service to get target application ID...

Cheers,

Shane

Worked this one out. Was a SharePoint 2016 bug with Secure Store Service and updating/refreshing the master key.

The action calls the secure store web service which tries to get update/refresh the key and fails when it can't.
