Contract content errors: tree

Codes that start with seampact/tree/ say your routes or schemas do not fit together.

Code	Cause and fix
seampact/tree/schema-unknown	A schema name is not declared. Declare it under schemas, or fix the name.
seampact/tree/required-unknown	required lists a property the object does not have. Declare the property or remove it from required.
seampact/tree/schema-cycle	A schema reaches itself without an object in between. Break the cycle with a named object.
seampact/tree/paging-style	A list names no paging style. Declare your page shape under pagings (the error shows an example) and name it in paging, or write paging: none. See Lists.
seampact/tree/paging-unknown	The style is not declared under pagings. Declare it or fix the name.
seampact/tree/path-param	A path holds {who} and nothing declares it. Declare it in pathParams.
seampact/tree/path-segment	A route path has a / at an end. Write relative segments with no / at either end.
seampact/tree/collection-singular	A collection with no id has no name to derive from. Add singular: note for the names it derives.
seampact/tree/format-unknown	The format is not a portable format. Declare it under scalars, or write a portable one such as uuid.
seampact/tree/api-version	The api version is a label such as v1, but the path has {version}. Write an integer, or set pathVersion: none.
