I am building some pharo scripts to edit tasks in the Asana.com system.

I have generated a Personal Access Token, and the terminal command of:

curl -H "Authorization: Bearer 12345abc" https://app.asana.com/api/1.0/users/me

Returns 200/ok, and the right data.

However, the pharo commands

tmp1 := ZnClient new.
tmp1 headerAt: 'Authorization:' put: 'Bearer 12345abc'.
tmp1 url: 'https://app.asana.com/api/1.0/users/me'.
tmp1 get.

Results in an authorisation error.��

I haven't tried using Zinc to access authenticated sites before, what am I doing wrong?

Cheers
Andy
