Hi There

I am able to launch stacks from the command line without problem but when I try from Horizon I get:

Error: ERROR: Property error : devserver: flavor Expecting to find username or userId in passwordCredentials - the server could not comply with the request since it is either malformed or otherwise incorrect. The client is assumed to be in error. (HTTP 400)

Using Wireshark the transaction between Horizon and Heat I see

Using Wireshark the transaction between heat and keystone I see

So I can see what what it is on about, the passwordCredentials are not passed from Horizon to Heat and null values are ... (more)
