application manager relies on nonexistent HTTPS endpoint

[noerw]

Currently, the HTTPS endpoint for the application manager API does not exist; to cite the docs:

A secure endpoint at https will follow soon.

this results in errors when trying to make requests:

{ FetchError: request to https://us-west.thethings.network:8084/applications/opensensemap-test failed, reason: write EPROTO 140413053495104:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:../deps/openssl/openssl/ssl/s23_clnt.c:794:

Don't know if this should be fixed, as keys should not be exchanged via HTTP anyway. Opening the issue anyway for others to see, as it took me some time to find out the cause.

Thanks for reporting @noerw. This is definitely something we need to support.

[johanstokking]

We're going to close HTTP at all and switch to gRPC

[mirk8xr]

@johanstokking Where I can find an example(or the docs) of gRPC node client that access to the application manager api? How authentication works?

[noerw]

Is support for gRPC in this node-app-sdk planned? when will it land?

[johanstokking]

@mirk8xr @noerw it's not out yet, but @romeovs will work on this. Please watch #54. I'm closing this issue because we're discontinuing HTTP on the Handler

[jpmeijers]

Damn. This means I have to change the TTN Mapper app to use gRPC too. Which is a hassle, because autogenerating java code from protobufs in Android studio doesn't work well.
