# Troubleshooting

> Debug common issues with the Payment Methods integration.

## Component not rendering?

**Verify component attributes:**

* `session-id` must be a valid session ID from the API.
* `amount` must be set.
* `customer-type` must be `NATURAL` or `LEGAL`.

**Check script loading:**

* Use `embed.src` from the session response. Do not hardcode the URL.
* The script must have `type="module"`.

## Session or API errors

**"Unauthorized" or 401 errors:**

* Session is invalid or expired. Create a new session.

**"Invalid session" errors:**

* Verify the session ID is the `id` value from the session response.
* Ensure the session hasn't expired.

## Payment method types

The following payment method types are supported:

* `RESURS_INVOICE`
