Wahoo iOS app generated fit file isse

[erwinfs]

Hi, Thank you for your very useful program.

I had an issue with a file generated by the Wahoo iOS app (files from my Garmin watch work fine). I printed the field names and units in add_dev_field_description:

field_name: calibration units: adc field_name: charge units: % field_name: running_smoothness units: % field_name: time_ms units: ms field_name: ant_device_num None field_name: crank_length units: mm x 10 field_name: glucose units: mg/dL field_name: avg_smoothness_x units: avg per/step field_name: avg_smoothness_y units: avg per/step field_name: avg_smoothness_z units: avg per/step field_name: travel_assist_level None field_name: lev_travel_assist_level_time_in_zone units: ms

The fields that lack units cause the problem.

Replacing line 453 in records.py with the following solved the problem for me if message.get('units'): units = message.get('units').raw_value else: units = ''

I have the same problem with a file recorded and exported from the Stava Android app. It seems that some messages don't have the unit field such that message.get('units').raw_value fails as described above.

An example message is: <DataMessage: field_description (#206) -- local mesg: #0, fields: [developer_data_index: 0, field_definition_number: 1, fit_base_type_id: string, field_name: activity_type]>

The issue can be fixed, by testing if the output from message.get('units') is equal to None.

if message.get('units') is not None:
    units = message.get('units').raw_value
else:
    units = None
