Many issues (solved/unsolved) on OFFLINE installation of EXB and questions related.
Dears,
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.
Solution :
After some digging, i just found out in the file :
client/dist/jimu-core/index.js
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).
Solution :
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 :
https://HOSTNAME:3001
https://HOSTNAME/arcgis_api_js/library/4.18
- 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 :
https://HOSTNAME/portal/sharing/rest/content/items/0686a4a2477d42c19ba838a317386875/info/null?token=XXXXXXXXXXX.
(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.
Best regards,
A.C
