Hi,

To use the sandbox Environment we must have the Partner Sandbox Environment License if you want to use the sandboxes for longer periods otherwise it will be expired, and need to create the new one.

refer to thinkaboutit.be/.../

Please Verify my answer if it helps you

I tried creating a new SandBox environment but now i am facing the below issue even when i don't have that app installed.

"Reason: The extension could not be deployed because it is already deployed as a global application or a per tenant application."

Can you share your launch.json and app.json file?

Hi BSSI_Vinay,

You just need to update the "version" in your app.json in VSCode

If its "version": "1.0.0.0", make it "version": "1.0.0.1"

Hi, just to add some info.

If you are customizing the AppSource extensio, please do not directly do it in the SaaS sandbox.
This may be the case if your extension has already been published in AppSource. Please use the Docker version.

Hope this helps.

Thanks.

You only need to increase the version in .App is okay. In my case, my boss uploaded a version larger than the version I was running to the Cloud, and the next day I had an error like you. What I do is increase my boss's version. Sorry, that is not the case. I'm wrong

Hi, that internal server error is normal. It happens sometimes — I have faced the same issue. Usually, after around 30 minutes, the sandbox automatically allows you to publish the extension.

In your case, you are also facing another error.

Here is some suggestions: Refresh sandbox instance

go to sessions:

check if any session is ongoing. if yes then directly close that session. after try to publish code.

you can restart environment and check
