Fixes #8944
This fix allows passing an
ObjectSchemacreated bySchema.object()tofunctionDeclaration.parameterswithout any TS errors. It also forbids passing a plain JSON object tofunctionDeclaration.parametersif it has anoptionalPropertiesproperty, as that is a convenience input method and should not be passed to the backend request. Users can still use therequiredproperty.I experimented with intercepting plain JSON objects passed to
functionDeclaration.parametersand processing theoptionalPropertiesinto arequiredarray but concluded there are too many places this needs to be done (on getGenerativeModel and on each of its methods, possibly on getImagenModel and others in the future) and it adds a lot of unneeded code for a case that can be handled simply by usingSchema.object()or manually filling out therequiredfield.
