Nothing happens after clicking "Add Migration" (error logs)

[Klusio19]

After I click "Add Migration" nothing happenes. I get little red LED icon in the Rider (exception).

Expected behavior: Opening GUI window.

• OS: Latest Arch Linux x86_64
• .NET SDK info 7.0.202
• Plugin version: 231.1.2
• Rider version: JetBrains Rider 2023.1 Build #RD-231.8109.212

VERY IMPORTANT: Problem occurs only on Linux Operating System. I currently run dual-boot setup with Windows, and on Windows with the same Rider and plugin version everything works fine. Exception information below:

java.lang.NullPointerException: Cannot invoke "com.intellij.notification.NotificationGroup.createNotification(String, com.intellij.notification.NotificationType)" because the return value of "com.intellij.notification.NotificationGroupManager.getNotificationGroup(String)" is null at me.seclerp.rider.plugins.efcore.features.shared.BaseCommandAction.notifyEfIsNotInstalled(BaseCommandAction.kt:93) at me.seclerp.rider.plugins.efcore.features.shared.BaseCommandAction.access$notifyEfIsNotInstalled(BaseCommandAction.kt:28) at me.seclerp.rider.plugins.efcore.features.shared.BaseCommandAction$actionPerformed$1.run(BaseCommandAction.kt:45) at com.intellij.openapi.progress.impl.CoreProgressManager.startTask(CoreProgressManager.java:429) at com.intellij.openapi.progress.impl.ProgressManagerImpl.startTask(ProgressManagerImpl.java:114) at com.intellij.openapi.progress.impl.CoreProgressManager.lambda$runProcessWithProgressAsynchronously$6(CoreProgressManager.java:480) at com.intellij.codeWithMe.ClientId$Companion.decorateFunction$lambda$10(ClientId.kt:329) at com.intellij.codeWithMe.ClientId$Companion.decorateFunction$lambda$10(ClientId.kt:329) at com.intellij.openapi.progress.impl.ProgressRunner.lambda$submit$3(ProgressRunner.java:252) at com.intellij.openapi.progress.impl.CoreProgressManager.lambda$runProcess$2(CoreProgressManager.java:186) at com.intellij.openapi.progress.impl.CoreProgressManager.lambda$executeProcessUnderProgress$13(CoreProgressManager.java:604) at com.intellij.openapi.progress.impl.CoreProgressManager.registerIndicatorAndRun(CoreProgressManager.java:679) at com.intellij.openapi.progress.impl.CoreProgressManager.computeUnderProgress(CoreProgressManager.java:635) at com.intellij.openapi.progress.impl.CoreProgressManager.executeProcessUnderProgress(CoreProgressManager.java:603) at com.intellij.openapi.progress.impl.ProgressManagerImpl.executeProcessUnderProgress(ProgressManagerImpl.java:60) at com.intellij.openapi.progress.impl.CoreProgressManager.runProcess(CoreProgressManager.java:173) at com.intellij.openapi.progress.impl.ProgressRunner.lambda$submit$4(ProgressRunner.java:252) at java.base/java.util.concurrent.CompletableFuture$AsyncSupply.run(CompletableFuture.java:1768) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.util.concurrent.Executors$PrivilegedThreadFactory$1$1.run(Executors.java:702) at java.base/java.util.concurrent.Executors$PrivilegedThreadFactory$1$1.run(Executors.java:699) at java.base/java.security.AccessController.doPrivileged(AccessController.java:399) at java.base/java.util.concurrent.Executors$PrivilegedThreadFactory$1.run(Executors.java:699) at java.base/java.lang.Thread.run(Thread.java:833)

Hi @Klusio19, the root cause of the issue is that Rider can't detect your EF Core Tools (dotnet ef) installed. If you installed them and still experiencing the same after Rider restart, you need to walk through the Microsoft .NET tools troubleshooting guide, this is common on Linux distros unfortunately.

The issue on our side is that it fails with an exception instead of notifying you properly, we will address that in terms of that ticket.

Hi! Thank you for you response! You were right! I was missing dotnef-ef. However the important thing is, I had Entity Framework installed, but not in a way it was recognizeable by Rider and Your plugin. Anyway, what I did was execute command dotnet tool install --global dotnet-ef. After that everything works like a charm. Like I said, it is somehow different from EF I had (executing dotnet ef (without the dash) spits out some info). Maybe (and I probably am) understanding something wrong (I am new to dotNet), but if someone will have the same problem as me, the solution is to instal dotnet-ef in a way I showed few lines above.
