The initialize request is sent as the first request from the client to the server. If the server receives a request or notification
|

before the initialize request it should act as follows:
|
||
|
|
|
||
|
|
1. For a request the response should be an error with code: -32002. The message can be picked by the server.
|
||
|
|
2. Notifications should be dropped, except for the exit notification. This will allow the exit of a server without an initialize request.
|
||
|
|
|
||
|
|
Until the server has responded to the initialize request with an InitializeResult, the client must not send any additional requests or
|
||
|
|
notifications to the server. In addition the server is not allowed to send any requests or notifications to the client until it has responded
|
||
|
|
with an InitializeResult, with the exception that during the initialize request the server is allowed to send the notifications window/showMessage,
|
||
|
|
window/logMessage and telemetry/event as well as the window/showMessageRequest request to the client.
|
||
|
|

The initialize request may only be sent once.
