Expression produces a union type that is too complex to represent

[tar-aldev]

Versions

• System: linux
• NodeJS: 14.16.0
• Typescript: 4.3.2
• Typegoose(NPM): ^7.6.0
• mongoose: <=5.10.18
• mongodb: ^3.6.9
  "@types/mongoose": "<=5.10.5",

What is the Problem?

Calling .create() on model gives an error:

error TS2590: Expression produces a union type that is too complex to represent.

It happens only in CI for some reason.

Code Example

The code is quite simple, so I don't think it is connected with our typedefinitions

// agreement type is defined as
AgreementFromForm & {
      ownerId: Types.ObjectId;
      createdBy: Agreement['createdBy'];
      createdAt: Agreement['createdAt'];
}

this.agreementModel.create({ // <- errors here
      _id: new Types.ObjectId(),
      ...agreement
});

code here

Do you know why it happens?

no
