SQL Extension Build Error ("Extension signature is not valid")

Eyad — Tue, 27 May 2025 19:24:05 GMT

Hi all,

I’m trying to build a SQL extension and was following the Dynatrace tutorial video. However, when I get to the build step, I encounter the following error:

{ "code": 400, "message": "Extension signature is not valid" }

Has anyone come across this issue before or know how to resolve it?

Thanks,

@EyadThere will be a step where you need to generate certificates and add the cert to credential vault in DT, was this step completed? You would need to use the same cert to sign and build the extension, I suspect this might be what's causing the error for you

I have generated the certificates and used it for custom Python extensions, and it worked. But the SQL is not building. for the Python I was using:
dt-sdk build --extra-platform manylinux2014_x86_64 .Because the building is happening on Windows, then deploying to Linux.
but for the SQL I am just using F1 key then option> Dynatrace extensions: Build
do you think this what causing the issue?

Double check your extension2.0 extension settings in VS Code.

In VS Code go to settings and search for: "@ext:DynatracePlatformExtensions.dynatrace-extensions"
