Calendar Library Event Reminders

[jmore (John More)]

I am trying to override event reminders. The setting in the event reminder structure ‘UseDefaut : false’ seems to have no effect. Sending the event reminder structure with just the overrides results in the following error

{“conferenceData”:{“createRequest”:{“conferenceSolutionKey”:{“type”:“hangoutsMeet”},“requestId”:“rrrr”}},“description”:“Link to create notes, Link to book next appointment. Instructions HTML Formatted”,“end”:{“dateTime”:“2018-11-01T21:00:00-04:00”,“timeZone”:“America/Toronto”},“reminders”:{“overrides”:[{“method”:“email”,“minutes”:120},{“method”:“email”,“minutes”:90},{“method”:“popup”,“minutes”:30}]},“start”:{“dateTime”:“2018-11-01T20:00:00-04:00”,“timeZone”:“America/Toronto”},“summary”:“Client Name Type of Service”}2018/10/31 08:14:27 The err googleapi: Error 400: Cannot specify both default reminders and overrides at the same time., cannotUseDefaultRemindersAndSpecifyOverride

I know this has something to do with the googleapi,MarshalJSON and setting ForceSendFields but nothing seems to work. Using the API explorer it is straight forward and works properly.

I realise my initial post was woefully inadequate and I apologise. Hopefully this followup will clarify.

I am using go version go1.11 linux/amd64 and the latest version of the Calendar API https://godoc.org/google.golang.org/api)/[calendar](https://godoc.org/google.golang.org/api/calendar/v3

I am trying to create an event that contains remainders as illustrated below and this code produces:
2018/10/31 08:14:27 The err googleapi: Error 400: Cannot specify both default reminders and overrides at
the same time., cannotUseDefaultRemindersAndSpecifyOverride

I have tried adding the UserDefault = false and setting the newEvent.ForceSendFields = []string{“UseDefault”} to no avail.

If I completely remove the remainders section the the call is successful and picks up the calendar default notifications even if I include the reminders UseDefault= false.

Using the API Explorer with the raw api works as expected so I am led to believe there is something wrong in the library.

You assistance is appreciated.

Thanks

Eureka!!! Nothing wrong in the library
The problem was, as usual; the user ::

newEvent.ForceSendFields = []string{“UseDefault”} 

Should have been

newEvent.Reminders.ForceSendFields = []string{"UseDefault"}

Using the ForceSend is not something I use every day (2nd time since I started with GO <6 months ago>) and it is resident on most library structures so be careful.

Hope this helps someone
