Thank you for the report... it probably is not being able to start up the language server (which is also probably the reason it's not working in the first place).

Do you have any non-empty .log files in:
C:\Users\<username>\.robotframework-ls?

If you do, can you attach them?

[sreejithrangarajan]

@fabioz : I checked the mentioned location but could only see empty .log files. If the language server is not started up will I still get syntax highlighting and other features? Because I'm able to see those for my robot files.

[fabioz]

You wouldn't be able to do that... what's the extension for the file you're having an issue with? (isn't it a .robot file?)

[sreejithrangarajan]

Yes its a .robot file. But the issue is not just specific to a file. When ever I startup the PyCharm IDE this exception pops up like this:

[sreejithrangarajan]

@fabioz Thanks a lot for the fix. Took the build with this fix from here and installed it using the steps mentioned in FAQ and now the issue is resolved. The IDE error is no longer occurring. Appreciating your fast response!

[fabioz]

Great, I was about to ask you to install that to check if it did indeed fix your case ;)

I'm going to publish an official release with this fix shortly now that you confirmed it worked.

[jessicaqgomez]

i have the same problem with this plugin, can you help me to solve it?

[fabioz]

@jessicaqgomez please create a new issue (as this one is fixed for quite a while, so, it must be a different thing).

Please provide the logs following the steps from: https://github.com/robocorp/robotframework-lsp/blob/master/robotframework-ls/docs/reporting_issues.md#intellij-logs
