Issue

I use Sentry and I get this TypeError:

Invalid schema configuration: Z is not a valid type at path dob. See https://bit.ly/mongoose-schematypes for a list of valid schema types.

Dob = date of birth, a string comes from the front end, from a datepicker so I coerce using Zod.

Code:

dob: z.coerce
      .date()
      .min(daysAgo(365 * 105), "Your date of birth appears to be invalid.")
      .max(daysAgo(365 * 18), "You must be 18 years or older.")
      .nullable(),

export const daysAgo = (days: number) =>
  new Date(Date.now() - days * ONE_DAY_MS);

This ultimately forms part of a modifyProfileSchema

export const modifyProfileSchema = z
  .object({

etc

I then:
export type ModifyProfile = z.infer<typeof modifyProfileSchema>;
and
export type Profile = ModifyProfile & { user_id: string; };
Before finally:

const modelName = "Profiles";
export const Profiles = mongoose.model<Profile & Timestamps>(
  modelName,
  new mongoose.Schema(
    {
...
dob: {
        type: Date,
      },
...

So it is sort of a non-issue, the data saves to the database - when I run it on local and interact with the front-end, it saves, pulls from the database but I constantly get this error from Sentry.

From the 'Z' in the error message I assume something relating to Zod is being passed back but no errors get thrown when I monitor it and ultimately the process works.

Let me know if anyone has any tips or insights.

Thank you.

I'm unable to repro, can you please modify the following script to demonstrate the issue you're seeing?

const z = require('zod');

const Profiles = mongoose.model(
  'Profiles',
  new mongoose.Schema(
    {
      dob: {
        type: Date,
      }
    }
  )
);

void async function main() {
  await mongoose.connect('mongodb://127.0.0.1:27017/mongoose_test');

  const modifyProfileSchema = z
  .object({
    dob: z.coerce
      .date()
      //.min(daysAgo(365 * 105), "Your date of birth appears to be invalid.")
      //.max(daysAgo(365 * 18), "You must be 18 years or older.")
      .nullable()
  });
  
  const { dob } = modifyProfileSchema.parse({ dob: new Date() });
  const { _id } = await Profiles.create({ dob });
  console.log(await Profiles.findById(_id).orFail().then(doc => doc.toObject()));
}();

Also, could you please provide the full stack trace of the error? The stack trace may provide something helpful. This error is indicative of trying to set the dob path in your schema to something Zod-related. For example, the following code would trigger the issue you're seeing: new mongoose.Schema({ dob: z.coerce.date() })
