$ref error Associating record in a Many-to-Many relationship Web API

(1) ShareShare
ReportReport
Posted on by Trent 9
I'm receiving the following error: The URI segment '$ref' is invalid after the segment <relationshipName>. I'm using the following Associate and disassociate table rows using the Web API (Microsoft Dataverse) - Power Apps | Microsoft Learn as an example for my call.  
 
My Code is below.  I've paused in the debugger to make sure on the call that the variables relatedEntitySetName, primaryEntitySetName, relationshipName, and the ids are set correctly.  Any idea what I may be doing wrong?
 
    var association = { '@odata.id': formContext.context.getClientUrl() + /api/data/v9.2/ + relatedEntitySetName + ( + relatedId + ) };
 
    var req = new XMLHttpRequest();
    req.open(POST, formContext.context.getClientUrl() + /api/data/v9.2/ + primaryEntitySetName + ( + primaryId + )/ + relationshipName + /$ref, true);
    req.setRequestHeader(Accept, application/json);
    req.setRequestHeader(Content-Type, application/json; charset=utf-8);
    req.setRequestHeader(If-None-Match, null);
    req.setRequestHeader(OData-MaxVersion/, 4.0);
    req.setRequestHeader(OData-Version, 4.0);
 
 
Apparently quotes are removed during posting.  Assume they're in their proper places.

    You can use my tool Dataverse REST Builder to generate the exact code based on your instance, one of the request type is "Associate"

    It seems you might have a formatting issue in your URI construction. 
    Ex...
    var association = { '@odata.id': formContext.context.getClientUrl() + "/api/data/v9.2/" + relatedEntitySetName + "(" + relatedId + ")" };
    var req = new XMLHttpRequest();
    req.open("POST", formContext.context.getClientUrl() + "/api/data/v9.2/" + primaryEntitySetName + "(" + primaryId + ")/" + relationshipName + "/$ref", true);
    req.setRequestHeader("Accept", "application/json");
    req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
    req.setRequestHeader("If-None-Match", null);
    req.setRequestHeader("OData-MaxVersion", "4.0");
    req.setRequestHeader("OData-Version", "4.0");

    Solved it. There are three things that you need to make sure of:
    1.) Give the relationship a name that is less than the max. Don't let the system truncate the name for you. (This is what was getting me)
    2.) Make sure you're using the relationship name, not the related table name (I tried both)
    3.) It's case sensitive.
