Hi,
I am trying to store a bearer token (obtained from a POST request to management.azure.com) for use in subsequent GET calls to the same API. I'm running into a problem though, I can successfully get the token and store it in a variable called 'access_token'. However, when I try and reference that variable from the other poller, it doesn't seem to want to pull the variable back and I continually get an 'InvalidAuthenticationToken' error.
My auth header looks like the below:

But that never works. If I manually add the live bearer token in place of $.['access_token'], the request works. My thought was that because the token is so long, is there a character limit being hit with the stored variable? If not, why am I not able to reference the token with that name?
Any help greatly appreciated as I have a number of things i'd like to monitor via API pollers.
Thanks,
Simon
