SonarLint connection issue: "Requested value 'BLOCKER' was not found"

SonarQube for IDE Visual Studio
1

Operating system:
Windows

Visual Studio version:
Visual Studio 2019

SonarQube for Visual Studio plugin version:
7.8.1.91542

Programming language you’re coding in:
C# (.NET Framework 4.5)

Is connected mode used:
Yes

SonarQube Cloud, SonarQube Server, or SonarQube Community Build? (if one of the latter two, which version?):
SonarQube Server Developer Edition v2025.3.1 (109879)

And a thorough description of the problem / question:

We are trying to use SonarQube for Visual Studio in connected mode with our SonarQube Server, but the connection fails.

When connecting from Visual Studio 2019, we encounter the following error:
“Requested value ‘BLOCKER’ was not found”

Our environment is:

  • Visual Studio 2019

  • SonarQube for Visual Studio 7.8.1.91542

  • C# (.NET Framework 4.5)

  • SonarQube Server Developer Edition v2025.3.1 (109879)

We also have another legacy environment using Eclipse Oxygen.3 with JDK 8, but this specific issue is currently observed from Visual Studio 2019.

According to your current documentation, Visual Studio 2019 can still run SonarLint / SonarQube for Visual Studio, but it is no longer officially supported. Could you please confirm whether this issue is caused by version compatibility between Visual Studio 2019 / plugin 7.8.1 and SonarQube Server 2025.3.1?

Could you also advise:

  1. Whether Visual Studio 2019 + plugin 7.8.1 is expected to work in connected mode with SonarQube Server 2025.3.1

  2. Whether this error is a known compatibility issue

  3. What version combination you recommend for a legacy environment like ours

Thank you for your support.

Hi,

Welcome to the community and thanks for this report!

The current version of SonarQube for Visual Studio (formerly SonarLint) is 10.1. Can you upgrade and see if this is still replicable?

And if it is, can we have a verbose log from IDE startup through to the error?

 
Thx,
Ann

This is Visual Studio 2019, which is not updated anymore with newer versions of SonarQube for Visual Studio - the last working version is 7.8.1. Only VS 2022 and VS 2026 get the latest versions of the IDE plug-in.

If I’m not mistaken, the issue you are facing @Ngoan_Tr_n_Thanh is due to diverging changes with newer versions of SonarQube Server and the IDE plug-in.

Nevertheless, please provide logs and screenshots if the issue was triggered in the UI! It would also be great to know whether or not you can still work / the analysis works if this issue happens.

Based on my own experience relying on VS 2015 (even older), it does not work in Connected Mode, so I’m limited to running these projects using Standalone Mode only. Would this be applicable to you? Of course, you miss out on the Connected Mode features, but this won’t raise any problems with incompatibility.

Hi Ann, EclipseWizard,

Thank you for your support and explanations.

We confirmed that we are using:

  • Visual Studio 2019

  • SonarQube for Visual Studio 7.8.1

  • SonarQube Server 2025.3.1

Based on your comments, it seems the issue is likely caused by a compatibility mismatch between the legacy IDE plugin and the newer SonarQube Server version.

For now, we will proceed with using SonarLint in standalone mode and continue using SonarQube analysis via CI.

Please let us know if you would still like us to provide verbose logs for further investigation.

Thank you for your support.

Hi,

It sounds like you’ve found an equilibrium, and there’s no need for further investigation. Thus, there’s no need for logs.

 
Thx tho!
