Malformed URI error for adTagUrl when evaluating video tags that include umlauts

[linkurzweg]

I am using the mediaProxy to update the ad tag url on entry change (see #4043). For example the video tags with {mediaProxy.entry.tags}. This works fine as long as there are no umlauts (ä,ö,ü...) in the tags.

When the video has tags that include umlauts, this will cause the player to not play the video, it loads indefinitely. Also the ad server returns an URI malformed error in the console:
ima3.js?_=1565696493160:40 Uncaught URIError: URI malformed at decodeURIComponent (<anonymous>) at Jc (ima3.js?_=1565696493160:40) at ima3.js?_=1565696493160:393 at Object.Sc (ima3.js?_=1565696493160:387) at Bu (ima3.js?_=1565696493160:388) at Cu (ima3.js?_=1565696493160:390) at Eu.k.Ef (ima3.js?_=1565696493160:393) at mw.DoubleClick.requestAds (load.php?debug=false&lang=en&modules=...)

It looks like the player is not correctly encoding umlauts when evaluating the tags?
Also I think the video should not stop working, even if there is a problem with the ad tag url.

@OrenMe maybe you could take a look at this? Thank you!

hi @linkurzweg the URI should contain valid characters and unfortunately we don't have a way to escape this via the evaluate tokens feature.

[linkurzweg]

@OrenMe thanks for the quick reply! I didn't know umlauts are considered invalid characters, since urls with umlauts do exist. I guess there is no way to disallow the entering of invalid characters in the Kaltura Console? Because that's gonna be a problem with all the different people adding content for our platform.

[OrenMe]

I'm not sure this is the issue :-)
Do u have a test link?

[linkurzweg]

I do have a test link, however I can't post that here. Can I contact you personally? Email?
Too bad there's no private messaging in GitHub anymore 🙄

[OrenMe]

please send to b6500e86.kaltura.com@emea.teams.ms

[linkurzweg]

Thanks! I will right now :)

[OrenMe]

@linkurzweg I think this might be an issue with how the player escape cust_params.
Are you a platform user? if so can you please file a support request?

[linkurzweg]

@OrenMe sorry, I am not... So how do we continue with this?

[OrenMe]

@linkurzweg I will open an issue in our internal bug tracker, but I do not have a due date for this yet.

[linkurzweg]

@OrenMe ok, thank you! I understand. Can you get back to me once this will be fixed (whenever that might be)?
