Hi <@U03D32VE95F>
What do you mean by "I have fields that need to be validated before registration completes.". Why not add the validation to the identity schema and have them validated by Kratos?

if you are doing a server-side rendered page, posting the data to Kratos, any errors thrown will redirect you back to the registration page (your server-side rendered page) through which you can get the errors using the flowId.

We have an example of this in <https://github.com/ory/kratos-selfservice-ui-node> which is used by the <https://www.ory.sh/docs/kratos/quickstart|quickstart>

Here is documentation on how to validate the input using the identity schema <https://www.ory.sh/docs/kratos/concepts/identity-schema#sanitize-usernamestraits>
