jsonwire-grid fails to provide session ID

[jg-repos]

I've followed your How-To guide using the config-local-sample.json configuration file. The grid boots up correctly, and the selenium jar is able to register a node; however, client never receives any session id from the grid when submitting the following POST.

curl -X POST http://127.0.0.1:4444/wd/hub/session -d '{"desiredCapabilities":{"browserName": "firefox"}}'

Instead the grid crashes with the following output

I'm eager to use your application, but I'm unfamiliar with go, so I'm unable to help fix this error. Can you please look into this error?

Note: I used the Dockerfile provided with the repository to install/run jsonwire-grid

Thanks

Thank u, @mrbub. We check it, but can u add to report your config file?

[jg-repos]

Sure, I stored it as config.json, contents below

{ "logger": { "level": "debug" }, "db": { "implementation": "local" }, "grid": { "client_type": "selenium", "port": 4444, "strategy_list": [ { "type": "persistent" } ], "busy_node_duration": "15m", "reserved_node_duration": "5m" } }

I should add that a session is created when registering with the hub using curl -X POST http://127.0.0.1:4444/wd/hub/session -d '{"desiredCapabilities":{"browserName": "firefox"}}'

A firefox WebDriver session opens, but no session details are returned to the client.
