Hello,

Here I'm fetching data using javascript FetchXML. and It works fine in an unmanaged package but it gives me an error in a managed package.

function getAPIRecordsByFetchXML() {
    try {

        var entityNameApi = "accounts";
        var fetchData = '<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false"><entity name="account"><attribute name="name" /><attribute name="primarycontactid" /><attribute name="telephone1" /><attribute name="accountid" /><order attribute="name" descending="false" /><filter type="and"><condition attribute="name" operator="eq" value="Account1" /></filter></entity></fetch>';
        var data;
        var serverUrl = "abc123.crm.dynamics.com";
        var req = new XMLHttpRequest();
        req.open("GET", serverUrl + "/api/data/v8.0/" + entityNameApi + "?fetchXml=" + fetchData, false);
        req.setRequestHeader("OData-MaxVersion", "4.0");
        req.setRequestHeader("OData-Version", "4.0");
        req.setRequestHeader("Accept", "application/json");
        req.setRequestHeader("Prefer", "odata.include-annotations=\"OData.Community.Display.V1.FormattedValue\"");

        req.onreadystatechange = function () {
            if (this.readyState == 4) {
                req.onreadystatechange = null;
                if (this.status == 200) {
                    data = JSON.parse(this.response);
                }
                else {
                    var error = JSON.parse(this.response).error;
                    alert(error.message);
                }
            }
        };
        req.send();
        return data;
    } catch (e) {
        alert(e.message);
    }
}

    Hi,

    Have you checked the url if it's pointing to the correct url? Also, make sure you have the same entity & attributes.

    Hi Chaaya Patel,

    The FetchXML needs to be in a format usable by the Web API service endpoint.

    See: https://www.hbs.net/blog/march-2017/using-fetchxml-in-web-api-queries-via-javascript-f

    Hope this helps.
