In docker logs librechat i get that errors:

2025-09-24 19:38:49 error: Invalid custom config file at /app/librechat.yaml:
{
"issues": [
{
"code": "invalid_type",
"expected": "array",
"received": "string",
"path": [

}
],
"name": "ZodError"
}
2025-09-24 19:38:49 warn: RAG API is either not running or not reachable at undefined, you may experience errors with file uploads.

librechat.yaml is defined:
version: "1.2.9"
endpoints:
custom:
- baseURL: "http://ollama:11434/v1"
apiKey: "" # Optional, leer lassen
models:
default: "deepseek-r1:8b-llama-distill-q4_K_M" # Standardmodell
options: # Optional: Liste der verfügbaren Modelle
- "deepseek-r1:8b-llama-distill-q4_K_M"
- "llama3.1:8b"

That is, why i want to use lokal LLM-Models. I find no way to do this.

My .env is:

what is wrong?
