OpenAPI `swagger.json` description is invalid
OpenAPI descriptions should be validated so that it can be used in automatic tools (to generate typescript model for instance)
CLI tools can be used to validate it as a test in the CI, for instance :
npx @redocly/cli lint https://icatplus.esrf.fr/swagger.json
Some web GUI also exist, for instance: https://editor.swagger.io/ (File > Import URL)
