I am trying to work on the corda openapi generation project but its showing me above error in the last step. The project I am trying to work is
https://blog.b9lab.com/cordacon-2019-highlights-braid-server-and-openapi-generator-for-corda-flows-api-s-d24179ccb27c and similar https://github.com/corda/openapi-sample
But the problem is that I have done same as show in the link but my last step that is generating api is not executing and throwing the above mentioned errors. And one more thing is that my one step is showing different output compared to the one shown in the Git.
MY OUTPUT

The difference is that their don't contains https but I don't think this could raise any error.
In your Braid server output it says activating OpenAPI V2
meaning your server is generating the API's with OpenAPI Specification version 2
, while your openapi-generator is throwing error ERROR io.swagger.v3.parser.util.RemoteUrl
meaning it's looking for v3
(not v2
) that's why it's unable to parse the file.
In my Medium article (and R3 tutorial) we both use v3
.
From my article (notice the 3
after 10200
:
localhost:10004 user1 test 10200 3 “/home/your-user/path-to-project/bootcamp-openapi/build/nodes/PartyA/cordapps”
From R3's article (notice how we both use openapi version 3
):
Now, find the down triangle to open up the run configuration. At the Program arguments, paste in:
localhost:10004 user1 test 10200 3
"/YOUR-PATH-TO-THIS-FOLDER/bootcamp-cordapp/build/nodes/PartyA/cordapps"
RPC connection address: localhost:10004
node login username: user1
node login password: test
Your desired expose port: 10200
openapi version: 3
Cordapp folder to pick up the jar: "YOUR-PATH-TO-THIS-FOLDER/bootcamp-cordapp/build/nodes/PartyA/cordapps"
So I'm not sure why you decided to use version 2
.
