makeWebRequest: bad request on some devices

Some devices got a bad request on next makeWebRequest: 

Communications.makeWebRequest("[email protected]/events",
{timeMin=>2020-4-30T12:19:00+02:00, timeMax=>2020-5-1T12:19:00+02:00},
{:method=>Communications.HTTP_REQUEST_METHOD_GET, :headers=>{ "Authorization"=>"Bearer "+"ya29…valid-oauth-token…
OpxLk" }}, method(:onEvents));

  1. in simulator it works fine
  2. in majority of devices it works fine
  3. the oauth token is valid: the login was confirmed and another request was successful
  4. Error 400: Bad Request on some devices: e.g.  iPhone X, iOS 13.4.1, Garmin Connect: 4.30
    1. same parameters work on
    2. the user even tested it works for his account in the simulator, but not in the device through his phone


  • by previous testing I realised in another request the device translated "showDeleted"=>false  to "showDeleted"=>0 and that was not accepted by Google on some devices while worked fine on most of them. So I fixed that one. 
  • but in the request above all the parameters are strings, so I don't see anything that can go wrong. 
  • from debugging couple of devices, I am almost sure the problem is caused inside the makeWebRequest. But I don't know what can go wrong. The debug data just looks good yet it replies with the Bad Request. 

What can be wrong there? 

The only idea I have is that it is something phone/app specific inside the makeWebRequest itself. 

Source, app.
