The community member is writing a crawler and noticed that another crawler allows selecting a proxy via the inputs. They have configured the proxy in their code but are unable to set it on Apify. The comments suggest that the community member should include the proxy parameter in their INPUT_SCHEMA.json file. Another community member mentions that they couldn't find a proxy example in the documentation or a full list of field types and editor types, and suggests checking an example actor for reference. The documentation on Apify's proxy is also provided as a resource.
