Any suggestion on how to tap snap applications?

First of all, I applaud your elegant approach!
I guess it's a simple issue, but my lack of golang skills prevents me from finding a workaround:
(Ubuntu 24.04.1)

$ curl -L https://github.com/monasticacademy/httptap/releases/download/v0.0.5/httptap_linux_x86_64.tar.gz | tar xzf -
...
$ sudo snap install helm --classic
...
$ sudo ./httptap -- helm search hub anything
cannot fstatat canonical snap directory: Permission denied
subprocess exited with code 1

Oh fascinating. Haven't tried it with snap in my testing. What if you try adding --no-overlay like this:

./httptap --no-overlay -- helm search hub anything

[astonchev]

Still the same unfortunately

$ sudo ./httptap --no-overlay -- helm search hub anything
cannot fstatat canonical snap directory: Permission denied
subprocess exited with code 1

Yeah I can reproduce this now. It looks like this is related to the user namespace that httptap creates, which is only necessary for non-root, so you should be able to do:

sudo ./httptap --no-new-user-namespace helm search hub foo

I think I can support this case better though... I'll look into making this work out of the box.

Confirm. Thank you so much for your work, Alex
