The checks are failing as of now since the php-http-client PR is not merged due to which setHost is not working.

The php-http-client PR is merged, however it is not released. That's why when make test-docker is run, the docker container is not able to pick the merged changes. I am attaching screenshots of the local environment where I manually made changes and the tests are passing.

We probably in all the examples should note that to use the EU region, their subuser must be pinned. One thing I'm wondering is if we should link to the docs for how subuser pinning will work. These do not exist yet publicly, so we may want a followup round to add a link to the documentation in example comments next quarter.

There do seem to be a lot of failing checks...

Makes sense, I can create a ticket to add the documentation link in all SDKs, when its available publicly.
