Hi there,

In UI VScode extension is not showing any validation issue.((OutPutStream issue))

Server is IO:

When i debug StreamMessageConsumer :consume() we convert to bytes and write to output stream.I can see data

I put a breakpoint in MessageReader.js to check Vscode client is getting data or not(Image attached).

I don't see data while debugging MessageReader.js seems in between data is lost or got cleared.

All this is happening in first request(initialize). Server is executing validations and etc. But in UI(Vscode Extension no output).

Any input will be appreciated.

Thanks
Nagaraj

Which Xtext version do you use.
How does your package json look like ?
How the extension

do you use custom Launcher?
Do you se the messages sent Server side
e.g. call org.eclipse.xtext.ide.server.ServerLauncher with args
-log debug -trace

the When i debug StreamMessageConsumer :consume() we convert to bytes and write to output stream.I can see data
part of your message i did not understand

@Christian Thank you for your quick reply.

Found root cause messageBuffer.js code was throwing error if header not contains :

I have corrected validation message.

Thanks

validation message was having CRLF and it was more than 3 lines. So messageBuffer.js was considering message as header.
I made changes to validation message.

Thanks

I thought of Overriding messageBuffer.js but subsequently I have to override other code to fix issue. So I have created a issue in VSC https://github.com/microsoft/vscode-languageserver-node/issues/1276

As a work around I have fixed my validation message which was having 3+ lines and CRLF.

It just a misinterpretation of validation message as header.

Thanks

I just fixed my xtext validation message.(made it 2 lines)

It just a misinterpretation of validation message as header in messageBuffer.js.
