Cannot convert an object of type Array{Any,1} to an object of type String

[nw11]

When running:

GoogleCloud.JSONCredentials("/home/nick/credentials.json")

I get the following error message.

ERROR: MethodError: Cannot `convert` an object of type Array{Any,1} to an object of type String

This is for Julia 0.7.0 - working off master branch, as current release doesn't precompile successfully.
I get a similar error message using Julia 0.6.4.

did you update the new release?
try again?

[JockLawrie]

Just tried this on master.
It works without any errors (on Linux).

ok, close here.
please reopen if you still have this error.
