Hi all. I run a set of new Favero Assioma Pro RS pedels. Power shows up fine in my charts but the PCO, left/right smothnes,… are missing.
I import these activities via Garmin Connect and if I download the original fit file I see the data in there. Not with all data points but with most. (verified with fitfile viewer)
Nevertheless I get Errors. See below.
Any ideas on how to resolve this?
Cycling metrics
TypeError: Cannot get property "0" of null
Left/right pedal smoothness
TypeError: Cannot read property "data" from null
time,watts,cadence,heartrate,distance,altitude,latlng,velocity_smooth,temp,left_right_balance,respiration,torque
Left/right pedal smoothness
SyntaxError: Variable “streams” has already been declared
Which chart are you using?
Here’s one that I use with my first gen Assioma’s
It’s a Custom chart that I added on the Power page
Basically the same 
But the script output on the config page of the chart throws:
Script did not return a value object
The last error from your first post can be avoided by placing brackets around the entire script {…}
This keeps the variables within the script. Seems like the variable ‘streams’ is already used in another script that is running on your account. It’s basically always a good idea to put the entire script in brackets unless you deliberately want to use a variable over different scripts.
Thanks for the quick reply. I tried the brackets but still no change. Sorry
I did some digging and is seems like Garmin Connect is not passing on all cycling dynamics data recoreded.
It passes on: left pco , right pco , left power phase , right power phase .
It does not pass on: left_pedal_smoothness , right_pedal_smoothness , left_torque_effectiveness , right_torque_effectiveness
Can you maybe describe your recording setup (pedal type, bike computer, backend infrastructrue like garmin connect, strava,…)
I have Assioma Duo latest firmware, Edge 840, Garmin Connect → Intervals.
If you can give me a download link for one of your files, I can check how it behaves in my Intervals config.
I use the Pro MX2 and can see these fields as standard (Fields)
- Left Smooth
- Right Smooth
- Left Torque
- Right Torque
The following are under Fields\Custom Streams:
- Left PCO
- Right PCO
- Left Power Phase
- Right Power Phase
You can quickly check what’s passed on with the Charts - Custom Streams - add stream menu
The dropdown will have all available streams.

Dear all. Thank you so much for all your inputs.
I was able to solve my issue. It was an issue with how I uploaded from Garmin to intervals.icu. It turns out that in the Garmin Profile I used, the Power Meter was connected via Bluetooth, but the extended cycling dynamics data which is needed here, is only available if ANT+ is used.
So I re-paired my pedals with Garmin via ANT+ → et voila.
