Getting 404 on calling invoke with Forge Tunnel

[Atif Dastgir]

Hi,

I have a created a basic app using this template https://developer.atlassian.com/platform/forge/build-a-hello-world-app-in-confluence.

It works fine when I deploy and install on my site. However, when I use 'forge tunnel', I'm getting a 404 error "Error: There was an error invoking the function - 404". I didn't make any changes to manifest etc. - just used the template code generated using 'forge create'

Can any guide what maybe causing this?

By debugging I found that whenever I run 'forge tunnel', it starts tunnel at a random port. When invoke is called, it redirects to localhost:8080/resolver - so there's a port mismatch. Is there a way to start tunnel with specific port?
