Power Apps Portal Web API "shell is not defined"

Posted on by CU29100325-0

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?

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.

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); } }); })
