AST error in generate client when using ClientForwardRefsPlugin

[akshats1998]

Hey! Currently when we import AriadneClient, it takes up about 400MB due to all the types, schemas. TO solve this we were hoping to use ClientForwardRefPlugin. However, on doing ariadne-codegen after setting the plugin we're getting the following error

Plugins to use: ariadne_codegen.contrib.no_reimports.NoReimportsPlugin,ariadne_codegen.contrib.client_forward_refs.ClientForwardRefsPlugin
