Setting Effort using effortAllocation

Hey folks!

I'm having some issues setting Effort using the API. Per the "tasks" page in the API Documentation, I'm trying to set a task's Effort using effortAllocation in a POST request, but the tasks will not upload if I include it. My JSON for effortAllocation is as follows:

effortAllocation: {
                "mode": "Basic",
                "allocatedEffort": 90,
                "totalEffort": 90
            }

I append that to my URI in JavaScript as follows:

encodeURI(`/api/v4/folders/${folder}/tasks?...&effortAllocation=${JSON.stringify(job.effortAllocation)}`)

Also of note:

• When I don't include effortAllocation, the tasks push into the desired folder just fine
• I have tried building my JSON object with just "mode" and "allocatedEffort", "mode" and "totalEffort" and, even just with "mode", but none of them have properly loaded
• Other JSON objects stringify without breaking the request
• I'm using a Wrike Enterprise Basic account, if that were to effect anything

Any help with this would be immensely appreciated!
