TypeError and Exception in queued task

Im having the below errors and am unable to ascertain where they stem from. Im using Meteoric package and updated to the latest Meteor 1.2+.

TypeError: Cannot read property ‘splice’ of null. Sometimes, ‘splice’ is replaced by 0

Exception in queued task: Error: Failed to execute ‘insertBefore’ on ‘Node’: The node before which the new node is to be inserted is not a child of this node.

I understand using ionic-autoforms may lead to the first error but I am not using the package at the moment. The packages I am using: Meteoric, reywood:publish-composite, simple:reactive-method and useraccounts.
