I get "Save failed due to an invalid html tag in a name or description"

[RussellTait4]

I know this is a stretch, but I am trying to enter into a description of a Story Map Tour, a tag like

 <br><a href="ArcGIS-trek2there://?stop=33.84470,-118.38576" target="_blank">Trek there</a>

it works in

https://esri.github.io/Trek2There/Trek2ThereWebLauncher.html

and is encouraged in things like Survey123.  See App links in Trek2There · Esri/Trek2There Wiki · GitHub 

I understand that this is a non-standard URL - is there a way to bypass your error catching (which I assume is in the Builder), apart from having to hand-roll and host the story ourselves?

thanks

Hi,

That does seem like a non-standard URL for an href. If a link doesn't work if you enter it into a web browser, I feel like it won't work in a Map Tour. 

I think this is unrelated to what you are entering but it is perhaps worth saying in relation to the error message that Map Tour is giving you. If you are uploading your pictures directly into the Map Tpur Builder, some additional HTML restrictions kick in, in addition to our standard ones, because the names and captions of your places are being stored in an ArcGIS feature service behind the scenes. For example we allow the hr tag for map tours unless you are using image upload because feature services don't allow that tag. That is one reason you may be able to use certain HTML in other ArcGIS apps but not in feature service based Map Tours. See if this FAQ helps too: https://storymaps.arcgis.com/en/faq/#question32
