Is it possible to make Zod throw custom errors rather than a ZodError?

[Victor-M-Giraldo]

I have a predefined error that occurs when there is a bad arg in an API call. Trying to move validation over to use zod. Could I instead make it so zod throws a custom error?

export class BadApiArgumentException extends OttException {
	name = "BadApiArgumentException";
	arg: string;
	reason: string;

	constructor(arg: string, reason: string) {
		super(`Bad argument: ${arg}: ${reason}`);
		this.arg = arg;
		this.reason = reason;
	}
}

You can define custom error messages and act and/or do stuff based on that.

const schema = z.string({
invalid_type_error: "This should be a string"
});

Is this what you are looking for?

class CustomException extends Error {
    public name = 'CustomException'

    constructor( public arg: string ) {
        super( `Bad argument: ${ arg }` )
    }
}

const result = z.string().safeParse( 123 )
if ( !result.success ) throw new CustomException( 'arg' )

If you found my answer satisfactory, please consider supporting me. Even a small amount is greatly appreciated. Thanks friend! 🙏
