Rasa X version 0.33.0 or higher is only compatible with Rasa Open Source 2.x. If you are on Rasa Open Source 1.x, please check the [compatibility matrix](https://legacy-docs-rasa-x.rasa.com/docs/rasa-x/changelog/compatibility-matrix) for a compatible version.

## Troubleshooting

Common errors you may encounter in a Rasa X installation.

### Failing requests

Rasa X sends data through HTTP headers, and sometimes the payload can be bigger than allowed on the default configuration. If your requests are failing, try increasing the header size limits.

As an example, on NGINX Controller ConfigMap.

```plaintext
http2-max-field-size: 8k

http2-max-header-size: 32k
```
