additionalProperties: [true/false] causes crash

[Marcondiro]

Hello,
The field additionalProperties of the Schema Object must be a JSON schema itself according to the specification, true and false are valid JSON schemas but they lead to a crash in EvoMaster.

java.lang.ClassCastException: class java.lang.Boolean cannot be cast to class io.swagger.v3.oas.models.media.Schema (java.lang.Boolean is in module java.base of loader 'bootstrap'; io.swagger.v3.oas.models.media.Schema is in unnamed module of loader 'app')

Other important info:

• version of EvoMaster (EM) used 1.6.1
• how EM is run (eg, if from JAR or from one of its OS installers) deb

hi,
thanks for reporting this bug.

Until fixed, you can try to run EvoMaster with --expectationsActive false (as it should deactivate that part of the code)

Thanks! 🙂
