Describe the bug.

Cannot generate code from the spec

Something went wrong: Template render error: (node_modules@asyncapi\generator\node_modules@asyncapi\java-spring-cloud-stream-template\template\src\main\java$$everySchema$$.java) [Line 10, Column 51] Error: Can't determine the type of property petType at eval (eval at _compile (node_modules@asyncapi\generator\node_modules\nunjucks\src\environment.js:527:18), :46:11) at node_modules@asyncapi\generator\node_modules\nunjucks\src\environment.js:510:9 at eval (eval at _compile (node_modules@asyncapi\generator\node_modules\nunjucks\src\environment.js:527:18), :12:11) at node_modules@asyncapi\generator\node_modules\nunjucks\src\environment.js:510:9 at Template.root [as rootRenderFunc] (eval at _compile (node_modules@asyncapi\generator\node_modules\nunjucks\src\environment.js:527:18), :367:3) at Template.getExported (node_modules@asyncapi\generator\node_modules\nunjucks\src\environment.js:508:10) at eval (eval at _compile (node_modules@asyncapi\generator\node_modules\nunjucks\src\environment.js:527:18), :11:5) at Environment.getTemplate (node_modules@asyncapi\generator\node_modules\nunjucks\src\environment.js:225:9) at Template.root [as rootRenderFunc] (eval at _compile (node_modules@asyncapi\generator\node_modules\nunjucks\src\environment.js:527:18), :9:5)
