Do you use the latest version of the plugin?

3

Hi Martin, if you mean the ice plugin, I’m using IntelliJ with Vaadin plugin version 1.4.3

Thanks

4

That’s strange!
Most of my apps are on 24.6.0 already, and I have no issues.

5

Hi Simon, may be cause I’m migrating from 14 → 24.6 and the app is quite complex.

I’m not on spring boot but Jakarta EE ( Planning to move to spring boot but is quite a long task )

6

Hi, 24.6 should work perfectly with IntelliJ plugin 1.4.3. One difference is that maybe application deployed on app container cannot do localhost rest requests directly - but that’s my blind guess.

7

Hi, I’m using tomcat 10 installed locally.

the error I receive seems regarding the rest communication

Needs investigation, I’ve created GH issue which you can follow [BUG] Cannot communicate with plugin while running on Tomcat · Issue #55 · vaadin/copilot · GitHub

Hi,

the error

[http-nio-8080-exec-4] ERROR com.vaadin.copilot.ide.CopilotIDEPlugin - Unable to communicate with IDE plugin
java.io.IOException: Unexpected response (400) communicating with the IDE plugin:
at com.vaadin.copilot.ide.CopilotIDEPlugin.sendRestSync(CopilotIDEPlugin.java:342)
at com.vaadin.copilot.ide.CopilotIDEPlugin.send(CopilotIDEPlugin.java:323)
at com.vaadin.copilot.ide.CopilotIDEPlugin.getModulePaths(CopilotIDEPlugin.java:307)

is an indication that something earlier on went wrong. The 400 response code is typically sent when the IntelliJ rest endpoint is flooded with more than ~30 requests per minute and a known cause for this is some unspecific problem in detecting the source folders for the project (also indicated by the error originating in getModulePaths.

To more easily figure out the source of the problem, the first exception would be useful to have, as it most likely is something else than only “bad request returned by the server”

Hi Artur, may be this can be useful, thanks
