Blank HTML generated - but correct schema present in Javascript objects

[frankjkelly]

Could be a bug could be just me as a newbie

Just got around from updating from the old npm and ag way of doing things to the new way.
Since I am on Apple Silicon and hit some issues I decided to use docker and mount all the files I needed

docker run --rm -it --user=root \
-v ./specs/services/compute.yml:/app/asyncapi.yml \
-v ./specs/schemas/schemas.yml:/schemas/schemas.yml \
-v ./specs/messages/messages.yml:/messages/messages.yml \
-v ./build/generated-docs/html/compute:/app/output \
asyncapi/cli generate fromTemplate -o /app/output /app/asyncapi.yml @asyncapi/html-template@3.2.0 --use-new-generator --force-write

I fixed all the issues in my schema and it runs without complaint

Generation in progress. Keep calm and wait a bit
[BABEL] Note: The code generator has deoptimised the styling of /libraries/node_modules/generator-v2/node_modules/@asyncapi/html-template/template/js/asyncapi-ui.min.js as it exceeds the max of 500KB.
Check out your shiny new generated files at /app/output.

but when I look at the generated output I see a header and no content. Any ideas? Using @asyncapi/html-template@3.0.0 I can see the full schema in the page source - see below

Environment: Apple Silicon

Please let me know if you need any more information

FYI I'm a JS newbie too but the first error I see in the JavaScript is here. No idea if this is helpful or not.

hey there, did you try other commands, like instead of generate fromTemplate -o /app/output /app/asyncapi.yml @asyncapi/html-template@3.2.0 --use-new-generator --force-write just do validate to see if other outputs work?

but to be honest - your command is completely fine so my guess there is something missing in your AsyncAPI document - maybe it is valid but do not provide the necessary data. Can you share it? best if you put it in https://studio.asyncapi.com/ and then grab a link using its sharing functionality and put a link here. Or just paste the document as markdown code here - whatever you prefer.

@derberg Thanks - unfortunately I'd be uploading some pretty sensitive information.
I think I am going to take another approach and roll back my changes back to asyncapi:2.0.0 and work through the errors

What's odd is I get so many errors in some schemas and not in others

Generation failed
Generator Error: Input is not a correct AsyncAPI document so it cannot be processed.

Is there some way to figure out which errors are critical e.g. the one's with should seem like they are warnings. The others I guess are errors.

What's really odd is this one

Diagnostic err: Property "oneOf" is not expected to be here in path ["channels","persistent://platform2/event/interaction","publish","message","oneOf"] starting L17 C14, ending L26 C78

I was pretty sure that oneOf was supported for a message
Foe example

channels:
  "persistent://platform2/event/interaction":
    publish:
      message:
        oneOf:
          - $ref: '../messages/messages.yml#/components/messages/endpointClosed'
          - $ref: '../messages/messages.yml#/components/messages/endpointCreated'
          - $ref: '../messages/messages.yml#/components/messages/endpointOpened'
          - $ref: '../messages/messages.yml#/components/messages/interactionClosed'
          - $ref: '../messages/messages.yml#/components/messages/interactionCreated'
          - $ref: '../messages/messages.yml#/components/messages/interactionOpened'
          - $ref: '../messages/messages.yml#/components/messages/interactionSegmentInserted'
          - $ref: '../messages/messages.yml#/components/messages/intervalOpened'
          - $ref: '../messages/messages.yml#/components/messages/intervalNext'

but when I remove

          - $ref: '../messages/messages.yml#/components/messages/intervalNext'

ALL the errors go away - so not really sure how to debug this if some of the errors are "false leads".

Any advice as to find which error is the root cause? Thanks!

can't you anonymize sensitive info? I would prefer not to bring my brain back into the past and v2 😄

when I look at below screen shot you shared, I immediately have 2 things to mention:

• I see servers and channels in the components. Components object is only for reusability, so do you have servers and channels in your file also as standalone objects on the root? (not visible in screen shot)
• I see you have AsyncAPI v3 but channel still uses subscribe semantics and oneOf for messages. This is not what it should be like in v3. I recall such errors whenever I ask chatGPT to generate AsyncAPI document v3 for me.
