- add .idea/ for Jetbrains IDEs
* in everything.ts
- remove import of SetLevelRequestSchema
- remove logLevel var
- add sessionId var
- in startNotificationIntervals function
- add optional sid argument
- set sessionId to sid
- define messages to be sent, adding sessionId if present
- remove setRequestHandler call for SetLevelRequestSchema
- replace server.notification calls that sent "notifications/message" objects with calls to server.sendLoggingMessage, passing just the parameters and sessionId.
* In package.json & package-lock.json
- bump TS SDK version to 1.17.5
* In sse.ts, pass transport.sessionId to startNotificationIntervals call
* In stdio.ts
- destructure startNotificationIntervals from createServer call
- implement custom logging request handler and server.sendLoggingMessage implementation, as a
workaround for the fact that the SDK's automatic log level handling currently only tracks requested log level by session id. This will be fixed in a followup PR for the SDK
- call the startNotificationIntervals function after connecting the transport to the server
* In streamableHttp.ts
- destructure startNotificationIntervals from createServer call
- call startNotificationIntervals passing the transport.sessionId after connecting the transport to the server
