Hi all,

I’m encountering an issue while uploading a Dynatrace Extension 2.0 bundle, receiving the error: “Extension signature is not valid.”

Steps taken so far:

1.I’ve placed the certification file&nbsp;in the Active Gate path:

```markup
/var/lib/dynatrace/remotepluginmodule/agent/conf/certificates/​

```

2.Extension 2.0 is enabled on the Active Gate.  
3. I have also used the appropriate sign commands during the bundle build process.

```markup
1.dt-sdk build --extra-platform manylinux_2_17_x86_64
2.dt extension assemble --src C:\Users\280380\vcleq\extension
3.dt extension sign --key secrets/developer.pem​

```

Has anyone faced a similar challenge or can suggest a way to resolve this issue? Any guidance would be greatly appreciated!

Thanks in advance!

Hi&nbsp;[@kpurimitla](https://community.dynatrace.com/user/75951)&nbsp;,

Have you [added the root certificate to the Dynatrace credential vault](https://docs.dynatrace.com/docs/shortlink/sign-extension#add-cert)? It’s necessary to sign an extension.

[Here](https://docs.dynatrace.com/docs/shortlink/sign-extension) is the whole documentation about sign extensions.

Hope it helps.

Regards,

Elena.

Thanks, Elena,

I don’t know how I forgot to add the certificate in the credential vault. Thank you so much for pointing that out! Now I’m able to upload the extension successfully.

Thanks again!
