I followed each step of [Deploy to a Server](https://rasa.com/docs/rasa-x/deploy/) and everything seems to be ok. Then, I used [Rasa X HTTP API Documentation](https://rasa.com/docs/rasa-x/api/rasa-x-http-api/) to add my nlu data, stories, domain, and config. But I couldn’t train a model because my config file contains a custom component named `datetime_parser`.

In my local, I placed `datetime_parser.py` next to `config.yml` but there is no `config.yml` file inside any of my containers. I tried to send `datetime_parser.py` file to `/app` folder of `rasa-x`, `rasa-production` and `rasa-worker` containers but nothing changed and I still have this error. What should I do now?

RASA\_X\_VERSION= 0.22.2

RASA\_VERSION=1.4.3

Error:

```auto
ERROR:rasax.community.api.blueprints.models:500, Internal Server Error, body='b'{"version":"1.4.3","status":"failure","message":"An unexpected error occurred during training. Error: Failed to find module \'datetime_parser\'. \\nNo module named \'regex\'","reason":"TrainingError","details":{},"help":null,"code":500}''

Hey @mac_71128, it looks like your `datetime_parser.py` file is trying to import a `regex` module, which should actually be `re`. Would you mind double-checking that?

Hi @fede. I fixed the regex problem but I still have `datetime_parser` error.
