What happened?

When setting the Random seed and then press Invoke I get the error message 'Server Error. Internal server error' in the web interface. When setting a manual seed the problem goes away and invoke generates an image. This always worked before, but some commit back this started to occur.

In the console window the following error is visible:

Are you on 3.0.2post1 or are you pulling from main? This error appears with an outdated frontend

If you're pulling from main on a developer install try this: 

> cd invokeai/frontend/web
> yarn install
> yarn build

and then in the root directory:

pip install -e .

After that, try restarting the server.

Hi Millu. Yes, I am pulling from main. I tried your commands and that solved the problem. It works again :). Thanks for the information and help.
