Signals Notebook : Attempting to create an entity through the API by referencing a template that hasn't been shared with the API user will results in a 404 error

When creating an entity through the API, the API user may reference a template eid that hasn't been shared with that user or their group.

This will return the following error:

{
    "errors": [
        {
            "status": "404",
            "code": "NotFound",
            "title": "The resource your required is not found."
        }
    ]
}

You can confirm if the template is shared or not by issuing the following API request:

/entities?includeTypes=experiment&includeOptions=template

If the template has not been shared go to:

SNCONFIG->System Objects-> Find the template in question->Click on the template and then click on Sharing on the top right.

Make sure it is shared directly with the API user or through a System Group.
