CDN Source pattern doesn't accept / anymore

Question

We configured our CDN rules engine to serve a SPA application (which means redirecting any request to the index.html page if it's not an asset or a static file).
Our rule was working well but we needed to update some condition on it. Validating it gave us this error

Of course, putting /. in doesn't work as expected but / isn't a valid source anymore. Neither do regex like /.+ or /*
Any feedback would be helpful to get a valid SPA rule back to work.

Thank you

Hello @Nicolas WEBER ,

I did some research and found similar issues with other customers which have already been reported to our product team. Preliminary investigation points out that this is a validation error only seen on the Azure Portal UI and is not a CDN bug.

To fix this issue at the earliest, we suggest that you use REST API to update the rule:

OR use Azure Resource explorer to edit the sourcePattern as below:

"actions": [  
            {  
              "name": "UrlRewrite",  
              "parameters": {  
                "sourcePattern": "/",  
                "destination": "/index.html",  
                "preserveUnmatchedPath": false,

The Product team will be fixing the Azure portal UI bug soon.

Kindly let us know if the above helps or you need further assistance on this issue.
