Haystack component with the name 'CustomComponent' not found.

[rudolpheric]

I have the following yaml-File with my custom component at the end (GetClientMessage) which I created:
`components:

• name: ElasticsearchDocumentStore
  params: {}
  type: ElasticsearchDocumentStore
• name: my_retriever
  params:
  document_store: ElasticsearchDocumentStore
  embedding_model: symanto/sn-xlm-roberta-base-snli-mnli-anli-xnli
  type: EmbeddingRetriever
• name: custom_cp
  params: {}
  type: GetClientMessage
  ...`

I created the file with the method

pipeline.save_to_yaml(path="../haystack/rest_api/custompipeline.yaml")

When I start my Rest-Server with docker compose up it brings up an error:

haystack.errors.PipelineSchemaError: Haystack component with the name 'GetClientMessage' not found. Check the class name of your component for spelling mistakes and make sure you installed Haystack with the proper extras: https://docs.haystack.deepset.ai/docs/installation#custom-installation

I also tried to copy paste my code into rest_api/pipeline/custom_component.py

My docker-compose.yml looks like this:

`haystack-api:

image: "deepset/haystack:cpu"
volumes:
  - ./rest_api/rest_api/pipeline:/home/rudolpher/rest_api/pipeline
ports:
  - 8000:8000
restart: on-failure
environment:
  - DOCUMENTSTORE_PARAMS_HOST=elasticsearch
  - PIPELINE_YAML_PATH=/home/rudolpher/rest_api/pipeline/custompipeline.yaml
  - TOKENIZERS_PARALLELISM=false

`

I had to change my docker-compose.yml. I think my question is a duplicate to #3673 (comment)

My new docker-compose.yml:

services:

haystack-api:
image: "deepset/haystack:cpu"
volumes:
- ./rest_api/rest_api/pipeline:/opt/venv/lib/python3.10/site-packages/rest_api/pipeline/
ports:
- 8000:8000
restart: on-failure
environment:
- DOCUMENTSTORE_PARAMS_HOST=elasticsearch
- PIPELINE_YAML_PATH=/opt/venv/lib/python3.10/site-packages/rest_api/pipeline/custompipeline.yaml
