When using oneOf with objects that have different properties, typescript assumes the list type and breaks about openapi3-ts HOT 4 CLOSED

Interesting case. Looks like the TS compiler is inferring the type of the list based on the first item of the list.
Did you tried to cast with as any to by pass TS inference checking?

@pjmolina I haven't but this error also happens if you switch the objects places

It works this way:

oneOf: [
   {
        type: 'object',
        required: ['status'],
        properties: {
          status: { type: 'string', pattern: JobApplicant.Status.NEW },
          payload: {
            type: 'string'
          },
        }
      } as any, {
        type: 'object',
        required: ['status'],
        properties: {
          status: { type: 'string', pattern: 'contact' },
        }
      }
]

As commented, looks like the case is related to the type inference on the TypeScript compiler.
Nothing can be done o this library to that respect. Forced casts as suggested can help to give hints to the TS compiler.
Thus, closing.
Feel free to reopen if we can improve it in any way.
