根因分析

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。

English

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

官方文档

解决方案

  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

无效尝试

常见但无效的做法:

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

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

  2. Adding public access to S3 bucket 85% 失败

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