I fixed it :) in case other people have this issue, is fixed as soon you execute something like this,
could you update the readme to add this? or even better if this can be automatically executed in the action.

docker buildx create --name mybuilder
docker buildx use mybuilder
docker buildx inspect --bootstrap

@segator,

or even better if this can be automatically executed in the action.

It's basically what this action do.
