No embeddingManager found in agent.services” when using AWS Bedrock setup

[anoosher1]

Hi ByteRover Cipher Team,

I’m running a PoC where we integrate Cipher (ByteRover) with AWS Bedrock as the backend for model inference.
However, when I start Cipher with npx cipher --mode mcp, I get the following log output:

14:12:10 INFO: [StorageManager:Cache] Connected successfully
14:12:10 INFO: InMemoryBackend connected
14:12:10 INFO: [StorageManager:Database] Connected successfully
14:12:10 INFO: [StorageManager] Storage system connected
No embeddingManager found in agent.services

It seems Cipher starts fine but fails to initialize the embedding manager.

My .env setup

# AWS Credentials
AWS_ACCESS_KEY_ID=<my_aws_key>
AWS_SECRET_ACCESS_KEY=<my_aws_secret_key>
AWS_REGION=eu-central-1
AWS_INFERENCE_PROFILE_ARN=<my_inference_profile_arn>

# Cipher settings
CIPHER_LOG_LEVEL=info
CIPHER_STORAGE=sqlite
CIPHER_DB_PATH=./cipher.db

# Models
CIPHER_EMBEDDING_MODEL=amazon.titan-embed-text-v2:0
CIPHER_LLM_MODEL=anthropic.claude-sonnet-4-20250514-v1:0

---

Context

• Using AWS Bedrock instead of OpenAI or Anthropic API keys.
• Cipher successfully connects to storage and cache.
• The inference profile ARN and Bedrock credentials are valid.

❓Question

Could you please clarify:

• What exactly triggers embeddingManager initialization in Cipher?
• Do we need to define anything else (e.g., embedding provider configuration or model alias) when using AWS Bedrock for embeddings?
• Is amazon.titan-embed-text-v2:0 expected to work as a valid embedding model, or should we specify it differently?

Any guidance on proper configuration for Bedrock-based embeddings would be greatly appreciated. 🙏

Cipher expects embedding models to be provided via a certain configuration variable. EMBEDDING_MODEL=...
not CIPHER_EMBEDDING_MODEL=... . (hope it works)

Hi I tried with as simple as below with as you Suggested with EMBEDDING_MODEL as below

AWS Credentials

AWS_ACCESS_KEY_ID=<key_id>
AWS_SECRET_ACCESS_KEY=
AWS_REGION=eu-central-1
AWS_INFERENCE_PROFILE_ARN=arn:aws:bedrock:eu-central-1:649233558552:inference-profile/eu.anthropic.claude-3-5-sonnet-20240620-v1:0

EMBEDDING_MODEL=cohere.embed-v4:0

I tried different embedding models like amazon.titan-embed-text-v2:0 and amazon.titan-embed-image-v1

Still the error is same as below

No embeddingManager found in agent.services

Can you just check . As per my understanding I have the permission to these models in my aws environment

[rohit20047]

in (.env file )
AWS_ACCESS_KEY_ID=AKIA...
AWS_SECRET_ACCESS_KEY=xxxxxx
AWS_REGION=eu-central-1

CIPHER_LOG_LEVEL=debug (while re run , you will get clear logs)
DISABLE_EMBEDDINGS=false (ensure it)

next ->( memAgent/cipher.ymal )
embedding:
type: aws-bedrock
model: amazon.titan-embed-text-v2:0
region: eu-central-1

if you get more logs please share I will try .
"No embeddingManager found in agent.services" will only happens if , if (agent.services && agent.services.embeddingManager) fails so...

After the suggested changes we could run it in MCP server mode ( http ) locally and could able to use with our IDEs using RooCode. Thank you for the support given.
