NullPointerException in ChannelManager.java

[meeshkan[bot]]

Hello!

@ginccc We believe we may have found a bug in labsai/EDDI.

The endpoint /channelstore/channels does not conform to the Swagger document at /swagger.json. The Swagger document marks the following fields as required in the POST request body:

[]

However, when running the following request, the server returned a 500 response:

curl -X POST --data "{\"name\": \"xhgifqpow\"}" "http://localhost:7070/channelstore/channels"

Here is the stack trace:

fixed.

expected behavior for

curl -X POST --data "{\"name\": \"xhgifqpow\"}" "http://localhost:7070/channelstore/channels"

is Bad Request, code: 400 Msg: Argument must not be null nor empty (channelDefinition.type)
