Undefined index: entity_from_field ... in ctools_entity_from_field_get_child()

For me, the error showed up in the same symptom.

This is a user error on Custom Page Settings Argument Context Assigned. The selected Context is broken:
Possible Reasons:
a) content panel / page / etc is changed/deleted;
b) Context type is invalid.
In either case, the 'child' cannot be found because the 'parent' name is not found/correct, even though validation has occurred (error is missed in validation).

Solutions: (in my case)
a) flushing cache to remove problem may work.
b) change the Context Type from node.id to node edit form: node ID

That has a related problem.

thanks @dvandusen. Your post helped to fix the error with a broken context.

Thanks @dvandusen! Removing a missing context fixed it for me.

@dvandusen, yep same here. Thanks buddy! 😉✨
