Description
Describe the bug
The problem arises when I deploy my spring boot webflux application on AWS lambda and then create an AWS gateway API for it. When I try to access /webjars/swagger-ui/index.html I get a blank page and also errors in the console.
The errors are:
Uncaught SyntaxError: Invalid or unexpected token (at swagger-ui-bundle.js:2:218114)
Uncaught SyntaxError: Invalid or unexpected token (at swagger-ui-standalone-preset.js:2:108540)
Uncaught ReferenceError: SwaggerUIBundle is not defined
at window.onload (swagger-initializer.js:5:3)

much information as possible: - A clear and concise description of what the bug is: the title of an issue is not enough
To Reproduce
Steps to reproduce the behavior:
I have included the dependency for swagger ui:
implementation 'org.springdoc:springdoc-openapi-starter-webflux-ui:2.5.0'
I also have a configuration file for swagger:
@OpenAPIDefinition
@Configuration
public class OpenApiConfig {
@Bean
public OpenAPI usersMicroserviceOpenAPI() {
return new OpenAPI()
.info(new Info().title("App API")
.description("API Description")
.version("1.0"));
}
}
I also have a request stream handler for aws lambda:
public class LambdaHandler implements RequestStreamHandler {
private static final SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
static {
try {
handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(AppGatewayApplication.class);
} catch (ContainerInitializationException e) {
// if we fail here. We re-throw the exception to force another cold start
e.printStackTrace();
throw new RuntimeException("Could not initialize Spring Boot application", e);
}
}
@Override
public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context)
throws IOException {
handler.proxyStream(inputStream, outputStream, context);
}
}
I have configuration for security and have already allowed request to swagger-ui.
- What version of spring-boot you are using?
The version of spring boot is 3.3.1 - What modules and versions of springdoc-openapi are you using?
I am simply using webflux-ui of version 2.5.0
Expected behavior
Obviously, I expected to get the swagger UI specification for my application. Instead, I just got a blank page.
