**List of steps to reproduce** (step by step, including full links if applicable):
* I set up a new Wikilambda installation
* Go to Special:ApiSandbox, run the first example for wikilambda_function_call
*
**What happens?**:
{
"error": {
"code": "wikilambda_function_call-not-connected",
"info": "Could not resolve host 'mediawiki_function-orchestrator_1:6254', probably because the orchestrator is not running. Please consult the README to add the orchestrator to your docker-compose configuration.",
"*": "See http://localhost:8080/w/api.php for API usage. Subscribe to the mediawiki-api-announce mailing list at <https://lists.wikimedia.org/postorius/lists/mediawiki-api-announce.lists.wikimedia.org/> for notice of API deprecations and breaking changes."
},

**What should have happened instead?**:
The function should be evaluated.
