We have a webapp(war) that embeds the Swagger UI working under Spring Boot 2.7.5 and springdoc-openapi 1.6.14. I am in the process of updating Spring Boot to 2.7.11 and all is working fine. When I try to update springdoc-openapi to 1.6.16 I see this error:
Unable to render this definition
The provided definition does not specify a valid version field.
Please indicate a valid Swagger or OpenAPI version field. Supported version fields are swagger: "2.0" and those that match openapi: 3.0.n (for example, openapi: 3.0.0).
After reading through the posts of people with the same problem, I started with hitting the /v3/api-docs URL, all I see is a long series of characters (kind of like an encrypted string). I switched back to springdoc-openapi 1.6.14 and hit /v3/api-docs and a valid json was returned. Then I tried springdoc-openapi 1.7.0 and it also exhibits the behavior of returning a long string of characters.
I need to solve the Swagger-UI display issue. I looked at the Swagger-ui projects but I am not familiar with React and js.
