We have a ERP application (Epicor) which provides a REST interface sitting inside of an II 8.5 (win server 2012R2). No problem doing POST/GET etc using Insomina (a desktop program similar to PostMan) In IIS we have enabled only Anonymous Authentication. However, the below request is getting a 401…

[image] CORS Issue with Epicor REST ERP 10 That’s Cross Domain Request Issue a Browser Security Feature. You can disable CORS in the web.config of your app servers. Add the following appSetting NOTE THIS IS A POTENTIAL …

Had that same issue when using an AppServer with SSO Enabled. Deployed a separate instance without SSO and used it for API Calls, worked fine. Yes @hmwillett and I enabled CORS, and did alot more for about 3hrs :slight_smile: – Turn off SSO, works no problem. We tried Browser Plugins, Header Modifi…

Yes. We understand the risk with CORS (we are a very locked down corporate network). But I am a newbie at IIS admin. Which folder would find that xml file, and where what might it be called. Also, our IT department (sometimes clueless on this) thinks we might need this to be added to IIS: …

We got I.T. to add the cors module, and I updated the the <system.webServer> section of the web.config but I am still getting an CORS error. Can you tell me what is wrong here? <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> </customHeaders> </httpProtoc…

I don’t know your whole scenario here, but if you are in control of this custom web app that is making the ERP REST Post calls, also make sure you also host the app on draper.com , thus avoiding CORS altogether. You can’t use wildcard- when passing credentials. You can specify one domain tho…

I suggested you to add settings in the other section: Add the following appSettings value: <add key="CorsOrigins" value="*" /> I did not use that module you added, so I don’t know what is wrong in it.

Hello Olga. You are correct, and our I.T. department was clueless. One should not add that Cors Module. Now I have a slightly different issue. Getting the content of the post GetNextJobNumber(). Here is my fetcher: const fetcher = (async () => { const url = 'https://epicorapp2.draper.com/ERP1…

Charlie, I would like to avoid the CORS issue, but we are unable to use the epicor app server as also the IIS content server, and even if we knew what folder on IIS to put web content for the Test (e.g. D:\Epicor\Websites\ERP10.1Test\Server\Web ) find that putting content there is still not visible …

You know, you might just have a bad web.config - Epicor by default ALWAYS sets atleast since 10.2 and I’ve even seen it in my 10.1.500.46 <add key="CorsOrigins" value="*" /> If you did not have that key you might want to take the web.config.template and compare it to your web.config - it is in the…

Well, I followed OLGA’s advice, look out all the httpProtocol sections, and only did the add to and it works. My issue was the await for the fetch for the javascript. This is method is now working for me (see below). my only remaining question is that I tried: To add a little bit of CORS protec…
