Failed to Start Community Server Connector.

[elvitin]

I can't start the extension in vscode-linux, the following message is presented to me:

Unable to start the RSP server: Extension backend error - rsp error - community server connector failed to start - typeerror: cannot read properties of undefined (reading 'map')

What information about my environment do I need to provide to troubleshoot this issue?

UPDATE, I managed to solve it! Adding the following line to my settings.json:

"java.home": "/home/cebola/.asdf/installs/java/openjdk-11.0.2/"

However, vscode tells me to use "java.jdt.ls.java.home" instead of "java.home":

This setting is deprecated, please use 'java.jdt.ls.java.home' instead.

Should I be concerned?

Same issue on VS Code windows v1.67.2, rpr-ui v0.23.11. @beept workaround worked for me.

How did you fix it on windows? I can't get it working by adding this at the end "java.home": "c:\Program Files (x86)\Java\jdk1.8.0_191"

"java.home": "/usr/lib/jvm/jdk1.8.0_202" in my case.

May be you need to restart the windows, or the server connector. it is a little confusing, but the config that work with the connector is that.

similar issue on ubuntu using sdkman have jdk 8 on the path but have 17 installed as well. using amzn jdks no project just from user settings.json:

{ "java.jdt.ls.java.home": "/home/developer/.sdkman/candidates/java/17.0.7-amzn/", "java.configuration.runtimes": [ { "name": "JavaSE-1.8", "path": "/home/developer/.sdkman/candidates/java/8.0.372-amzn/", "default": true },{ "name": "JavaSE-17", "path": "/home/developer/.sdkman/candidates/java/17.0.7-amzn/" } ], "files.autoSave": "afterDelay", "redhat.telemetry.enabled": true, "rsp-ui.enableStartServerOnActivation": [ { "id": "redhat.vscode-community-server-connector", "name": "Community Server Connector", "startOnActivation": true, "rsp-ui.rsp.java.home": "/home/developer/.sdkman/candidates/java/17.0.7-amzn/" } ] }

My understanding is that the actual undefined reference was fixed back in November: * | 5c8a74c - Safety check all calls to .map for null arrays, see vscode-server-connector/issues/557 (6 months ago)

Regarding java.home or java.jdt.ls.java.home, our specific key has been changed to rsp java.home last July: see Commit 849975d0968cd89032c3e4eab5155a465eb587f0

But we still check java.home and java.jdt.ls.java.home for backup values.

@tim-oe please show me the actual error you receive. Most of the above errors should have been fixed long ago.
