Payload not updated when using request.error filter

[llindemann]

Describe the Bug

When updating the payload in a flow or an extension using the request.error filter, the changes are discarded

To Reproduce

The following script should prevent fields with a must be [null] validation to display an error message to the user:

module.exports = async function(data) {
	if (Array.isArray(data.$trigger.payload?.errors)) {
			const errors = data.$trigger.payload.errors.filter(a => !a.message.includes('" must be [null]'))
            return {errors}
	}
    return {};
}

But the error message is displayed to the user.

This should have either been an action or should ahve have updated its output, nice catch 😄

From what I gather, this is due to a small bug in the error-handler, corrected by #17003. It works for my use cases, but maybe I miss some side effects
