makeWebRequest: bad request on some devices

https://forums.garmin.com/developer/connect-iq/i/bug-reports/makewebrequest-bad-request-on-some-devices?CommentId=0afa464f-13fb-47f6-83cc-77c5bdc16f11

In makeWebRequest, I am getting a 400 if I am in a +GMT timezone and it works successfully in a -GMT timezone using the GoogleAPIs for calendar events. According to https://stackoverflow.com/questions/30294500/google-calendar-api-doesnt-accept-datetime-with-positive-utc-offset/58860565#58860565, "+" needs to be encoded as "%2B"

Thanks

Good investigation.

Unfortunately in my case there is another API call that insists on POST params, so this workaround is not enough for my case and some devices still fail.

Namely it's https://oauth2.googleapis.com/token call.

This bug is specific to a mobile phone app. I have one watch that works with Android phone app but not with iPhone app. Other users keeps reporting this bug as well.

Thanks for sharing your findings though. It might help some.

Thanks FlowState. Updated the call to use params and no longer getting 400s.

As a workaround can you put the query string in the url yourself, instead of using the params option of makeWebRequest?

e.g.
```
Communications.makeWebRequest(
  "https://www.googleapis.com/calendar/v3/calendars/[email protected]/events?" +
  "timeMin=2020-4-30T12:19:00%2B02:00&" +
  "timeMax=2020-5-1T12:19:00%2B02:00", 
  null // params has to be null for this to work
  ...
 );
```
I realize it's not ideal, but this might get you unblocked while you wait for a resolution on the device side.

Based on this thread, I think this should work (you can a query string in the url or a non-null params arg, but not both at the same time):
