Thanks!
I was also able to recreate the issue within Chrome & Safari. Firefox works fine for me 🤷‍♂️
I’ve submitted this issue with Mapbox & I’ll keep everyone up to date here with how things play out:
>
>
> Perhaps there's just an upper limit to the size/number of \`featureCollection\` la…yers that can be added to a map?...
>
> \*\*mapbox-gl-js version\*\*: 0.44.0
>
> \### Steps to Trigger Behavior
>
> 1. Visit https://citystrides.com/users/5560/map with Safari or Chrome on a Mac (I don't have a Windows computer to test with, and the page loads successfully with Firefox)
> 2. The base Mapbox map loads, but the red lines do not
> 3. View the console & see the error
>
> Compared to a functional page...
>
> 1. Visit https://citystrides.com/users/1/map
> 2. View base Mapbox map along with the red lines
>
> \### Expected Behavior
>
> A map should display with tons of red lines on it. The red lines are a bunch of encoded polyline layers.
>
> \### Actual Behavior
>
> The layers don't draw & the console contains an error.
>
> Error as reported in Chrome:
>
> \`\`\`
> evented.js:109 Error: RangeError: Maximum call stack size exceeded
> at Actor.receive (actor.js:81)
> Evented.fire @ evented.js:109
> \`\`\`

> Error as reported in Safari:

> \[Error\] Error: RangeError: Maximum call stack size exceeded.

> \### Further Details
>
> \- Raw encoded polyline array for non-functional page: \[polylines.txt\](https://github.com/mapbox/mapbox-gl-js/files/1691906/polylines.txt)
> \- The user for the \[functional page\](https://citystrides.com/users/1/map) linked above has more individual encoded polylines than the non-functional user, so it doesn't seem to be a count limit
> \- Since it's likely not a layer count issue, the only two possibilities I can think of are
> - \*\*size\*\* - perhaps the non-functional user has larger individual encoded polylines than the functional user
> - \*\*data integrity\*\* - perhaps the non-functional user has one/some encoded polylines that are 'broken' somehow
**Small Update:** I’ve found that it’s something within Mapbox’s code… An older version of their plugin works properly, while later versions do not. I’ve left the old version in place - so you should all be able to see your LifeMap again. I’ll continue working with Mapbox to see if I can help figure this out for their future versions.
