When using the nintex form web part with a custom master page, we are able to add it to the page and configure it properly, however, when viewing the page as a user, we are getting the error: "Object reference not set to an instance of an object" in the place where the web part should be.
I've seen the various postings for SharePoint 2013 suggesting the WebPartPages control be moved to the body section of the master page and other variations of that like moving this bit of code before the s4-workspace div:
<!--SPM:<SharePoint:AjaxDelta id="DeltaSPWebPartManager"runat="server">--> <!--SPM:<WebPartPages:SPWebPartManager runat="server"/>--> <!--SPM:</SharePoint:AjaxDelta>--> <div id="s4-workspace" class="s4-nosetwidth">
None of the above actually resolves the problem in SharePoint 2016 though. The forms web part displays on the page per usual if I reset it back to the out of the box master page, so there's definitely something missing from the custom master page. Is there any other guidance available on what lines of code MUST be present in the master page for it to function properly? Also worth noting, not seeing anything useful in the ULS logs either.
Thanks,
