Getting lots of org.eclipse.lsp4j.jsonrpc.ResponseErrorException #580

Phillipus · 2021-12-09T11:23:13Z

Sorry, no particular steps to reproduce. I'm working normally in Eclipse 4.22 but the error log shows lots of these exceptions:

nothing else in error log of the remote site? which file types are you working with?

Phillipus · 2021-12-09T12:56:06Z

No, nothing. I'll try and see what might trigger it. I think it may be related to editing an Eclipse *.target file.

cdietrich · 2021-12-09T13:00:25Z

then i guess this is a bug in the language server for target files. dont know if that one will write logs to disk somewhere

cdietrich · 2021-12-09T13:04:23Z

@laeubi @mickaelistria do you have an idea which ls is used for target files?

mickaelistria · 2021-12-09T13:07:05Z

.target are XML files, so it's lemminx.

laeubi · 2021-12-09T13:09:38Z

.target are XML files, so it's lemminx.

I don't think this is true in general as Target files seem to have some special folding / coloring and code-actions so maybe there is something in between.

cdietrich · 2021-12-09T13:09:50Z

@mickaelistria i see the same logged locally. is there a way to see server side log or enabling it?

Phillipus · 2021-12-09T13:17:03Z

No, nothing. I'll try and see what might trigger it. I think it may be related to editing an Eclipse *.target file.

I was also editing a pom.xml file in the m2e editor. I need to try and trigger this again...

mickaelistria · 2021-12-09T13:17:08Z

The Language Server are enabled upon document creation; even if the editor is not the Generic Editor.

You can get the messages log (between client and server) in Preferences > Language Servers > Logs. This allows to see the message, and -potentially- to indentify a message that LSP4J cannot process (this can happen when there are "breaking changes" in LSP4J so a message sent from a server using an older LSP4J cannot be read by client using newer one).
For server-side logs, there is no user switch, you'll have to take the code of Wild Web Developer and configure the necessary logging options in the piece of code that starts LemMinX process. However you can set the org.eclipse.wildwebdeveloper.xml.internal.debugPort system property (see https:/eclipse/wildwebdeveloper/blob/master/org.eclipse.wildwebdeveloper.xml/src/org/eclipse/wildwebdeveloper/xml/internal/XMLLanguageServer.java#L75 ) and then attach a debugger to the LS directly.

As mentioned, I think it can be an incompatible message (LemMinX uses LSP4J 0.11.0) https:/eclipse/lemminx/blob/0.18.1/pom.xml#L11

Looks like eclipse/lemminx#1132.

cdietrich · 2021-12-09T13:33:14Z

yes

cdietrich · 2021-12-09T13:38:29Z

wonder if its intentional not to log everything on lsp4j side

Phillipus · 2021-12-09T13:39:47Z

Also getting lots of java.util.concurrent.TimeoutException and java.net.URISyntaxException: Illegal character in path at index 33: file:/Users/username/dev/Eclipse 4.22.app/Contents/Eclipse/configuration/org.eclipse.osgi/414/0/.cp/cache/www.w3.org/2001/xml.xsd

Open *.target file
Switch to "Source" tab
Start editing

Log attached
errorlog.txt

Phillipus · 2021-12-09T13:42:22Z

And the ResponseErrorException occurs when I close the *.target file.

pisv · 2021-12-09T14:00:32Z

As far as I can see, lsp4j is not even present in stack traces in the error log. Could you please report these issues to the affected projects: WildWebDeveloper or LSP4E? Thanks!

Phillipus · 2021-12-09T14:06:33Z

Yes, I thought it was connected.

eclipse-wildwebdeveloper/wildwebdeveloper#752

pisv · 2021-12-09T14:24:31Z

Closing as unrelated to lsp4j. The main issue described by the author is a known bug in lemminx.

I don't know the answer, but would a separate issue be a better place to discuss it?

Phillipus · 2021-12-09T14:29:59Z

OK. Can you tell me which plug-in in my Eclipse installation lemminx is used that causes this? I can see this plug-in - org.eclipse.m2e.editor.lemminx_1.18.3.20211116-0804

pisv · 2021-12-09T14:41:20Z

It looks like any plug-in that uses lemminx is potentially affected, until the error is fixed in a new version of lemminx. Unfortunately, I don't know exactly which Eclipse plug-ins use lemminx. Just looking at the name, it may be org.eclipse.m2e.editor.lemminx, but probably there are others too.

Thanks for the info. :-)
