Using arelle 1.2020.05.10 (64-bit) git master branch, with Python 3.6.9. Installed Edgar Renderer 36.0.2 git master branch. Opening a iXBRL file either from local machine or through URL does not open an internet browser to show the iXBRL document. I am able of starting the "Arelle web services" and connecting to localhost:8080. But I would prefer to have the browser triggered from Arelle GUI.
No visible errors in terminal. In Arelle message I see:
[Warn] "The rendering engine was unable to produce output due to an internal error. This is not concidered an error in the filing.
Browser works from Arelle by loading master on both Arelle and Edgar Rendered, + installing all required python package dependencies.
