Problem: Amazon Bedrock Error - "ModelNotFoundException" When Calling InvokeModel

Problem:  Amazon Bedrock Error - "ModelNotFoundException" When Calling InvokeModel

Problem:

When calling the InvokeModel API in Amazon Bedrock, you might encounter this error:

$ aws bedrock-runtime invoke-model \
    --model-id anthropic.claude-v2 \
    --body '{"prompt": "Hello, world!"}' \
    --region us-east-1

An error occurred (ModelNotFoundException) when calling the 
InvokeModel operation:
Requested model is not available

Issue:

This error occurs when the model ID is incorrect, the model is not deployed in the region, or the AWS account lacks the necessary access. Common causes include:

• Incorrect Model ID – Ensure the exact spelling of the model ID.
• Model Unavailable in the Region – Some models are restricted to specific regions.
• Model Requires Approval – Some models need AWS approval before use.
• Expired Model Version – Older versions of models may be deprecated.

Fix: Verify Model ID, Availability, and Access

# Step 1: Confirm the Correct Model ID
aws bedrock list-foundation-models --region us-east-1

# Step 2: Check Model Deployment in Your Region
aws bedrock list-foundation-models --region us-west-2
aws configure set region us-west-2

# Step 3: Verify Your Model Access Permissions
aws bedrock get-model-access --model-id anthropic.claude-v2

# Step 4: Verify Model Version
aws bedrock describe-model --model-id anthropic.claude-v2

# Step 5: Retry Your API Call
aws bedrock-runtime invoke-model \
    --model-id anthropic.claude-v2 \
    --body '{"prompt": "Hello, world!"}' \
    --region us-east-1
