Golang Error: undeclared name: ModelMap

Swagger-codegen version

Swagger declaration file content or url

https://raw.githubusercontent.com/skeleton1231/selling-partner-api-models/main/models/catalog-items-api-model/catalogItems_2022-04-01.json

Command line used for generation

swagger-codegen generate -i catalog-items-api-model/catalogItems_2022-04-01.json -l go -o /Users/huanghaitao/go/src/amz-sp-api-gosdk/catalog-items-api-model

Should I use interface ?

package swagger

type ModelMap map[string]interface{}

Reproduce the generation using the linked catalogItems_2022-04-01.json declaration and the reported swagger-codegen command. Inspect the generated Item model and the Go templates or model definitions responsible for ModelMap; done means the generated package defines or references that type consistently and builds without the undeclared-name error.
