:date: 2017-10-23 ======================== Monday, October 23, 2017 ======================== I continued to work on :ticket:`1275`. Here are some error messages I have seen today. :: {error: "idpiframe_initialization_failed", details: "Not a valid origin for the client: http://127.0.0.…itelist this origin for your project's client ID."} {error: "idpiframe_initialization_failed", details : "Not a valid origin for the client: http://127.0.0.1:8000 has not been whitelisted for client ID .... Please go to https://console.developers.google.com/ and whitelist this origin for your project's client ID."} I went to the Google console and added http://127.0.0.1:8000 to the *Authorised JavaScript origins*. This didn't help at first. But when I tried again two hours later, it worked. So it seems that Google needs some time to update the Web application after a change of configuration. Next error message was this:: { "error" : "invalid_request", "error_description" : "Permission denied to generate login hint for target domain." } Thanks to `this `__. I changed my URL from http://127.0.0.1:8000 to http://localhost:8000 and added added also http://localhost:8000 to the *Authorised JavaScript origins*.
