Swagger UI - management API - GET requests with body

[ndywicki]

Overview of the issue

Hello Team,

When I try to fetch the Spring Boot Actuator APIs (/management) with Swagger UI, there is an issue about the GET request have a body.

Stacktrace:

swagger-ui-bundle.js:6 TypeError: Failed to execute 'fetch' on 'Window': Request with GET/HEAD method cannot have body.
    at swagger-ui-bundle.js:6
    at c (swagger-ui-bundle.js:79)
    at Generator._invoke (swagger-ui-bundle.js:79)
    at Generator.e.<computed> [as next] (swagger-ui-bundle.js:79)
    at o (swagger-ui-bundle.js:51)
    at s (swagger-ui-bundle.js:51)

I'm not sure where come from the Open API specifications : http://localhost:8080/v2/api-docs?group=management but the GET request have a parameter in "Body" like "additionalProp1, ..."

Example:

Motivation for or Use Case

thanks for reporting this @ndywicki
I already saw this issue too, but not sure we can do something, as the API comes from Spring Boot

[github-actions]

This issue is stale because it has been open 30 days with no activity.
Our core developers tend to be more verbose on denying. If there is no negative comment, possibly this feature will be accepted.
We are accepting PRs 😃.
Comment or this will be closed in 7 days

I confirm this issue which is quite annoying. This is 100% caused by Swagger UI itself which fills out the request body with this sample text: {"additionalProp1":"string","additionalProp2":"string","additionalProp3":"string"}. I think I can find a workaround.

Hello,

Just for information is the same on the Jhipster-lite (v0.0.12-SNAPSHOT) Swagger UI ;-)
But strangely no fetch error, only the badly interpreted the ProjectDTO schema:

Could be a clue

[pascalgrimaud]

Yes it's normal, as the swagger ui here is managed only by the backend, so no manual fix has been applied :)
