The example is fully functioning and it can be run using the following command: This added a useful feature to JMESPath: the ability to filter a list based on evaluating an expression against each element in a list. Prob 0 1 Example from Michael Pfeiffer In OpenAPI 3. For example – we need to change the master page – for this even though the “SharePoint Server Publishing Infrastructure” is activated in site collection level but we won’t be seeing the change master page UI from the Site setting page – in this case we need to access the shortcut URL of changing the master page.
