Invalid CORS Request on Viya

AllanBowe — Sat, 25 Jan 2020 16:30:14 GMT

After following the instructions here I have whitelisted all domains as follows in SAS Environment Manager:

I have also restarted the Web Server as described here: https://documentation.sas.com/?docsetId=calsrvpgm&docsetTarget=n00004viyaprgmsrvs00000admin.htm&docsetVersion=3.4&locale=en

However when making local javascript ajax calls from a same-origin-policy disabled browser I still get the following response:

This issue can be reproduced by visiting the following fiddle (in a CORS enabled browser instance), modifying line 18, opening developer tools, running the code and viewing network tab.

Can anyone advise? How do I whitelist / use localhost when building web apps on Viya?

Hi Allan,

I am not sure about what is happening with CORS , but am curious regarding your headers - aren't you missing a client id : secret ? How have you registered your app (is it with password or impicit flow ) ?

Thanks for the input. I'm calling JobExecution services that were created at the backend using the client:secret (see https://github.com/macropeople/macrocore/blob/master/viya/mv_getapptoken.sas)

In any case I think I found the issue in this usage note: https://support.sas.com/kb/63/516.html

It says to restart ALL services. Will report back soon.

That did it. For reference, just run:

sudo /etc/init.d/sas-viya-all-services stop
sudo /etc/init.d/sas-viya-all-services start
