Power Apps Portal Web API "shell is not defined"

(0) ShareShare
ReportReport
Posted on by CU29100325-0 5

The documentation for the portals web API includes this JavaScript wrapper for calling the API from within a portal construct.

(function(webapi, $){
	function safeAjax(ajaxOptions) {
		var deferredAjax = $.Deferred();

		shell.getTokenDeferred().done(function (token) {


Although my portal version is well above the required version 9.2.6.41 and I believe I've set up the pre-requisites, and this code block does get entered, I always get an error "shell is not defined" from the shell line.

Does anyone know what could cause that?

    this works, another alternative would be run the script until the dom is completely loaded...

    $(function(){

	(function(webapi, $){
		function safeAjax(ajaxOptions) {
			var deferredAjax = $.Deferred();
				
			$.ajax(ajaxOptions)
				.done(function(data, textStatus, jqXHR) {
					validateLoginSession(data, textStatus, jqXHR, deferredAjax.resolve);
				}).fail(deferredAjax.reject); //AJAX
		
	
			return deferredAjax.promise();	
		}
		webapi.safeAjax = safeAjax;
	})(window.webapi = window.webapi || {}, jQuery)

		
	webapi.safeAjax({
			type: "GET",
			url: "/_api/cbs_estimationlines",
			contentType: "application/json",
			success: function (res) {
					console.log("completed")
					console.log(res);

		}
	});
	
})

    After further attempts, I think the issue is that shell is not available from within Web Form steps.

    In fact, I am able to remove the token-getting code and execute a delete via ajax without it. It seems that when in a form context, the token is already taken care of and so we don't need the shell to get it.

    (function(webapi, $){
	function safeAjax(ajaxOptions) {
		var deferredAjax = $.Deferred();

        // removed call to shell.getTokenDeferred()

		$.ajax(ajaxOptions)
				.done(function(data, textStatus, jqXHR) {
					validateLoginSession(data, textStatus, jqXHR, deferredAjax.resolve);
				}).fail(deferredAjax.reject);

		return deferredAjax.promise();	
	}

	webapi.safeAjax = safeAjax;

})(window.webapi = window.webapi || {}, jQuery)

webapi.safeAjax({
		type: "DELETE",
		url: "/_api/annotations(00000000-0000-0000-0000-000000000000)",
		contentType: "application/json",
		success: function (res) {
		},
		error: function(res) {
			console.log("error", res);
		}
  });


    The cookie containing the verification token gets sent with the ajax request anyway.
