undefined keyword error in pycharm robot framework

i am using pycharm with intellibot and robot framework plugins. one of a sudden, keywords turned undefined like "click element". but other robot framework libraries works well.

com.intellij.diagnostic.PluginException: getComponentAdapterOfType is used to get com.intellij.psi.impl.PsiManagerImpl (requestorClass=com.millennialmedia.intellibot.psi.RobotPsiManager, requestorConstructor=public com.millennialmedia.intellibot.psi.RobotPsiManager(com.intellij.psi.impl.PsiManagerImpl)).

Probably constructor should be marked as NonInjectable. [Plugin: com.millennialmedia.intellibot]

I am facing same issue but it got resolved by the following steps.

1. Go to https://github.com/lte2000/intellibot/blob/develop/intellibot.jar
2. Download the jar file
3. Open PyCharm -> Settings -> Plugins -> Click on Setting Icon (Right side from the Installed tab) -> Select Install plugin from Disk
4. Import the jar file in PyCharm editor
5. Click on Restart

Intellibot plugin exception still continue, but I fixed undefined keyword problem by installing "IntelliBot @SeleniumLibrary Patched" plugin.

This answer might be too late, but here we go

I faced the same issue. additionally, pycharm wasn't recognizing some of the keywords.

1. My plug-in was version IntelliBot 0.10.143.381 (pycharm plugin marketplace)
2. On Intellibot GitHub the latest version is 0.13.191.8026

So.

1. I uninstall the old plugin.
2. Download the release version on Github
   https://github.com/lte2000/intellibot/releases/tag/v0.13.191.8026
3. Install the new version

Now everything is working, no more error notifications and no more problems with the syntax highlight
