Validation error for empty strings

[zirkelc]

Hi,

the validator throws an error if a string property is empty, e.g. phone = ''. I defined the property phone on the model as follows:

phone: {
  type: 'string',
  required: false,
}

I get the following error stack trace:

        phone: ''},
     annotate: [Function] } }

I understand that this validation error comes from another library, however, I was wondering if there's a parameter which can be passed to enable empty strings. Otherwise, what is the desired outcome for required: false?

Thank you for sour support!

Have you tried using the empty rule?

phone: {
  type: 'string',
  required: false,
  validation: { empty: true },
}

Personally I would clean the object so you're not storing empty strings

I don't see the validation property in VSCode intellisense, but could be due to the reason I'm using TypeScript. Thats what I see:

With cleaning the object you mean remove the property from the object or set it to undefined?

I was able to suppress the TypeScript error message for validation with a //@ts-ignore comment
However, now I get the following error:
