I have installed EXB v1.3 , in Offline mode connected to a portal.
Problem 1 : Solved :
First i couldn't access the interface, an error message was displayed :
"Experience Builder developer Edition requires an ArGIS organization account with user type that includes privileges to create content"
(From client/dist/jimu-core : roleError2).
I was trying to connect with Portal administrator account (so full rights) on the experience Builder. I tried 3 accounts with various permissions but none was able to connect.
After some digging, i just found out in the file :
On line 28, Col 134408 there is a request on portal to "ValidateAppAccess" :
var a = 0.portal+"/oauth2/validateAppAccess?clientId="+t;
The t variable in the request is a string which contains the NAME of the application (printed in the console : "experienceBuilder").
The rest request "ValidateAppAccess" requires an AppID. So by changing the t variable with o.clientId :
var a = 0.portal+"/oauth2/validateAppAccess?clientId="+o.clientId;
The Interface showed up.
Problem 2 : Solved :
After those steps, i tried to create an application, when I added the map widget and tried to load a WebMap already prepared (from Portal).
The Widget keep spinning loose.
I had the same issue as @DaveFullerton on the CMD prompt (only once) :
server error read ECONNRESET
I had several Error Message in my Browser Console (look at the attached file : Console_error_COR.png).
After looking in the documentation, I've seen that API 4 assumes that CORS is enabled on server. I have enabled CORS requests on my IIS (Config_XML_CORS.png) and the problem was solved, but two points intrigues me :
- Why do we need CORS for the same domain :
- Why would the builder need CORS to load the API files (when the WebAppBuilder Dev Edition doesn't need it) ?
Problem 3 : Unsolved :
When the map widget is initiated with various Webmapps, the switch icons are not well set (look at the attached file : WebMap_icon_fail.png).
It appears that the source image is a request on the portal rest but the request is false :
(Where token is an available token)
The request return an error 404 :
I stopped digging, but i suspect many requests to be false when trying to reach portal informations.
So here are my questions :
Is it an issue that API JS 4.X can't load in the experience Builder or is it a normal behavior which need CORS enabled or proxy set-up ?
Why are the requests wrong, are they made for Online set-up ?
The last thing I'd like to report, it's the slowness of the refreshing layers when the experience is started or when the extent/zoom is reset.
I don't have an answer, but have had similar problems (not exactly the same though). A question - it sounds like you're connecting to ArcGIS Enterprise (on premise portal), not ArcGIS Online? If so, which version of Enterprise are you using?
Hi @Anonymous User ,
The "https://HOSTNAME:3001" and "https://HOSTNAME" should be considered as two domains I think.
The reason why the CORS is required is: EXB is using system.js to load scripts dynamically. For security reason, system.js add “script.crossOrigin = 'anonymous'”, but this property requires the CORS headers
Indeed HOSTNAME and HOSTNAME:PORT are considered as different domains for requests. It still is strang that WebAppBuilder Developper doesn't need CORS to acces API while using a different domain.
Thank you for the answer, but would you mind to developp "for security reason" pls ?
