CORS Issue when trying to access Public featurelayers

MohamedMezian1

Hey

We're using the Arcgis Map on our website with the 4.xyz arcgis Javascript library, imported into Angular.

Works on most maps but in some cases, while we are trying to load Public maps published by NOAA Office for Coastal Management we are getting a Cors error. Did they voluntarily block external domains from importing their featurelayer? Isn't their map public, so free to import on other maps ?

Thanks

Hi Mohamed Mezian‌,

Check whether you are using in mixed mode (http/https) ?

Best Regards,

Thanks for your responses. What I don't get is other layers seem to load fine. And they work in localhost.

I am thinking that perhaps they have restricted domain names.

Hi Mohamed Mezian,

I have bad experience with Angular cors issue error before and it's turn out working perfectly in dojo and jquery.

And found out Angular http get/post payload and different domain preflight check working differently from other js framework. But I didn't manage to fix that time.
