API Call Works In Browser But Not In Script

Question

I am working on a script that renames a OneNote Notebook. I have an API call that works when I run it in the browser but when I run it in the script it does not.

The API call is dynamic based on the name of the patient and their ID. In this case "Test, Test 123456". I get the API call from the Console.

In code I build the following and output it to the console:

https://site.sharepoint.com/_api/web/lists/getByTitle('Documents')/items?$select=Id,FileRef&$filter=substringof('/Shared%20Documents/Patients/Test, Test 12346/2.%20Daily%20Notes/Patient a',FileRef)

This outputs.

<?xml version="1.0" encoding="utf-8"?><feed xml:base="https://site.sharepoint.com/_api/" xmlns="http://www.w3.org/2005/Atom" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns:georss="http://www.georss.org/georss" xmlns:gml="http://www.opengis.net/gml"><id>04a45f71-c9ea-4e27-b447-afab53db054f</id><title /><updated>2019-08-13T15:05:34Z</updated><author><name /></author></feed>

I then use this code in the AJAX:

url: _spPageContextInfo.webAbsoluteUrl+"/_api/web/lists/getByTitle('Documents')/items?$select=Id,FileRef&$filter=substringof('" + onenote_path + "/2.%20Daily%20Notes/" + onenote_to_rename +"',FileRef)",
                type: "GET",
                headers: {
                    "accept": "application/json;odata=verbose",                    
                    "content-Type": "application/json;odata=verbose"                    
                },

With this I am taken to the error function.  I do not know what is different and why there would be an issue.

Thanks,
