  "message": "Authorization failed or requested resource not found"
}

A data scientist has the following IAM policy in the root compartment:
Allow group DataScientists to manage ai-services-generative-ai-family in compartment AIResources

A data scientist in group DataScientists uses the OCI Generative AI SDK to start a fine-tuning job in compartment AIResources. They receive the error shown. What is the most likely cause?

⚠ Common exam trap

Candidates often assume the error is about group membership or compartment existence, when in fact the fine-tuning job's dependency on Object Storage permissions is a classic oversight in OCI IAM policy configuration.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The fine-tuning job requires additional IAM policies for accessing the training data in Object Storage.

The error message indicates a permissions issue related to accessing training data in Object Storage. When using the OCI Generative AI SDK to start a fine-tuning job, the data scientist's IAM policies must explicitly grant read access to the bucket and objects containing the training data. Without these policies, the API call fails even if the user is in the correct group and the compartment exists.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
The compartment AIResources does not exist.
Why it's wrong here
If the compartment didn't exist, the user would get a different error (e.g., 404).
✗
The fine-tuning API is not yet available in that region.
Why it's wrong here
API availability would cause a 404 or 501, not a 403.
✓
The fine-tuning job requires additional IAM policies for accessing the training data in Object Storage.
Why this is correct
The policy must also grant permissions on Object Storage buckets containing the training data.
✗
The data scientist is not in the DataScientists group.
Why it's wrong here
If not in the group, the error would be a more generic 403; the policy is defined for the group.
