To reproduce the problem:

• visit https://openliberty.skillsnetwork.site/quicklab/ol-masterclass-1
• login the Skills Network
• follow the following instructions instead of the lab instructions
  • open a new command-line session -> select Terminal > New Terminal from the menu of the IDE and run:

    git clone https://github.com/OpenLiberty/open-liberty-masterclass.git
    cd open-liberty-masterclass/finish/barista
    mvn liberty:dev

  • Open another new command-line session -> select Terminal > New Terminal from the menu of the IDE and run:

    cd open-liberty-masterclass/finish/coffee-shop
    mvn liberty:dev

  • select Launch Application from the menu of the IDE, a box will appear where the port number is required. The application is running on port 9080. The Open Liberty homepage will load.
  • visit /openapi/ui similar to https://accountname-9080.theiadocker-1.proxy.cognitiveclass.ai/openapi/ui
  • try the POST request
  • will get 500 Error: Internal Server Error

We can open issue to SN network if it need to fix something.

[gkwan-ibm]

The problem is starting from SN. https://accountname-9080.theiadocker-1.proxy.cognitiveclass.ai/openapi/ui starts by https, it forwards to http://localhost:9080/..., and the orderCoffee endpoint use uriInfo to construct an URI to call another endpoint. That produced the scheme to be https,http,http and exception.

Phu gave us a workaround by setting <webContainer trusted="false"/> to the coffee-shop server.xml.

@pmd1nh @andymc12 you can keep this issue to fix the code to throw 400 instead of 500 error. Or, you can close this issue.

Thanks
