Root Cause

Insufficient IAM permissions for the S3 bucket when LlamaIndex attempts to persist index data to cloud storage.

中文

当LlamaIndex尝试将索引数据持久化到云存储时，IAM权限不足以访问S3存储桶。

Workarounds

  1. 95% success Update IAM policy to include s3:PutObject and s3:PutObjectAcl permissions for the specific bucket: {"Effect": "Allow", "Action": ["s3:PutObject"], "Resource": "arn:aws:s3:::your-bucket/*"} 
    Update IAM policy to include s3:PutObject and s3:PutObjectAcl permissions for the specific bucket: {"Effect": "Allow", "Action": ["s3:PutObject"], "Resource": "arn:aws:s3:::your-bucket/*"}
  2. 90% success Switch to local persistence: storage_context.persist(persist_dir='./storage') instead of S3 
    Switch to local persistence: storage_context.persist(persist_dir='./storage') instead of S3

中文步骤

  1. Update IAM policy to include s3:PutObject and s3:PutObjectAcl permissions for the specific bucket: {"Effect": "Allow", "Action": ["s3:PutObject"], "Resource": "arn:aws:s3:::your-bucket/*"}
  2. Switch to local persistence: storage_context.persist(persist_dir='./storage') instead of S3

Dead Ends

Common approaches that don't work:

  1. Setting AWS region to us-east-1 in boto3 config 95% fail

    Region mismatch doesn't cause AccessDenied; it's a permission issue, not location.

  2. Adding public access to S3 bucket 85% fail

    Public access violates security best practices and doesn't address missing IAM policy.
