Arrays without the option "type" or "items" makes array "Mixed" (adding array in array)

Versions

• NodeJS: 12.0.0
• Typegoose(NPM): 7.x.x
• Typegoose(GIT): commithash
• mongoose: 5.9.20
• mongodb: 3.5.9

What is the Problem?

Arrays prior to 7.1.0 are stored correctly. In versions later than 7.1 each element is nested in an own array:

Code Example

class Example {
  @prop()
  public arrayExample!: string[]
}

const arrayExample: ["1","2","3"]

new Example({arrayExample}).save()

My expectations in DB are:

{
   _id: ...,
   arrayExample: ["1","2","3"]
}

Its instead:

{
   _id: ...,
   arrayExample: [["1"],["2"],["3"]]
}

Do you know why it happenes?

no

[smolinari]

class Something {
  @prop({ items: String })
  public languages?: string[];
}

Note the items:String.

@henhen724 please give an example on how you try to set it (btw, did you try to do type: [String]? when yes, this is only available since 7.4.0)
