Uncaught TypeError when loading rides and route

Hi,

I can't seem to load the past rides and routes of my devices. I receive the following error in Chrome console.

app.min.js:49 Uncaught TypeError: Cannot read property 'get' of null
    at g.convertValue (app.min.js:49)
    at F.speedConverter [as convert] (app.min.js:6)
    at Function.eval [as initializeFn] (eval at makeInitializeFn (ext-all.js:22), <anonymous>:33:12)
    at g.constructor (ext-all.js:22)
    at new g (ext-all.js:22)
    at F.defaultRecordCreator (ext-all.js:22)
    at F.extractRecord (ext-all.js:22)
    at F.extractData (ext-all.js:22)
    at F.extractData (ext-all.js:22)
    at F.readRecords (ext-all.js:22)

On the modern interface, I am able to load the rides without a problem.

Try debug version of the web app by opening debug.html. it should give a more readable stack trace.

When I log in, I get an immediate error:

SpeedUnits.js:42 Uncaught TypeError: Cannot read property 'get' of null

When I load a route (history: this week):

SpeedUnits.js:42 Uncaught TypeError: Cannot read property 'get' of null
    at constructor.convertValue (SpeedUnits.js:42)
    at constructor.speedConverter [as convert] (AttributeFormatter.js:39)

    at constructor.callParent (ext-all-debug.js:12493)
    at constructor.extractData (ext-all-debug.js:90454)

Have tried to debug further, but it remains difficult. It's trying to convert a value which is empty?

Maybe attributes are null/undefined?

I don't have any (custom) attributes defined, related mysql sheets are empty.

Device attributes example:

{"batteryLevel":100.0,"distance":9634.51,"totalDistance":1781079.72,"motion":true}

I've tried making an export, and it works. In xlsx all the items are not null.

I guess you can just debug it directly from the web browser and see what's missing.

I can't find it. The following is the maximum amount of feedback I receive, and this is on the debug page.

In the database, nothing seems missing, and on the beta new dashboard I cán retrace the route..

I meant literally debug the code and check the values.
