Something went wrong: Template render error

[josejamilena]

Hi. I'm trying to generate code, but I don't understand the error in the template. Could you check if it's my problem or if there's a problem with the template?

Something went wrong: Template render error: (C:\Users\JAMILENADAZJ\eclipse-workspace\asyncapi\tmp\node_modules\@asyncapi\java-spring-cloud-stream-template\template\src\main\java\$$schema$$.java) [Line 53, Column 12] TypeError: Cannot read property 'items' of undefined at Object._prettifyError (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\lib.js:36:11) at C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:561:19 at eval (eval at _compile (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:631:18), <anonymous>:29:11) at C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:611:9 at Template.root [as rootRenderFunc] (eval at _compile (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:631:18), <anonymous>:740:3) at Template.getExported (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:609:10) at eval (eval at _compile (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:631:18), <anonymous>:28:5) at Environment.getTemplate (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:277:9) at eval (eval at _compile (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:631:18), <anonymous>:26:5) at eval (eval at _compile (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:631:18), <anonymous>:23:1) at fn (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\a-sync-waterfall\index.js:26:24) at C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\a-sync-waterfall\index.js:66:22 at executeSync (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\a-sync-waterfall\index.js:8:15) at C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\a-sync-waterfall\index.js:65:11 at eval (eval at _compile (C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:631:18), <anonymous>:18:1) at C:\Users\JAMILENADAZJ\AppData\Roaming\npm\node_modules\@asyncapi\generator\node_modules\nunjucks\src\environment.js:569:11

Welcome to AsyncAPI. Thanks a lot for reporting your first issue.

Keep in mind there are also other channels you can use to interact with AsyncAPI community. For more details check out this issue.

Hi Jose. The reason it fails is that you do not have fully correct AsyncAPI document.
In your document, in Server Object you specified Security Requirement Object

    security:
      - apiKey: []
      - supportedOauthFlows:
        - streetlights:on
        - streetlights:off
        - streetlights:dim
      - openIdConnectWellKnown: []

According to the spec:

The name used for each property MUST correspond to a security scheme declared in the Security Schemes under the Components Object.

You are basically missing Security Scheme Object in Components Object. For some valid example of how to do it properly, you could have a look here

@josejamilena I hope that helps, let me know

What is concerning me here though is, that the error you got was on a template lever, not parse level. For the parser your document is fine, which I don't believe it is true if the spec says securitySchemes is a must.
@fmvilas what you think, I think it is a bug in the parser and that in this case it is parser responsibility to validate it. I would move this bug under the parser repo, what say you? Error will occur in other templates too, like HTML -> https://playground.asyncapi.io/

Agree @derberg. I just listed it here: asyncapi/parser-js#10. Thanks!
