[Bug]: Multimodal data does not get stored in specified S3 bucket - AWS Knowledge Base

[srishtigulechar]

Terraform Core Version

1.8.5

AWS Provider Version

5.86.0

Affected Resource(s)

aws_bedrockagent_knowledge_base
supplemental_data_storage_configuration

Expected Behavior

aws_bedrockagent_knowledge_base has support for multimodal storage when parsing strategy is enabled. This can be configured using supplemental_data_storage_configuration block. Once terraform apply is run, the knowledge base should get created with s3 bucket for multimodal storage destination. When sync runs and gets completed, multimodal data from documents should be stored in that s3 bucket.

Actual Behavior

Once terraform apply is run, the knowledge base gets created with s3 bucket for multimodal storage destination. But when sync completes, no multimodal data gets stored in specified s3 bucket and it does not throw any permission errors either.

Steps to Reproduce

• Create aws_bedrockagent_knowledge_base with supplemental_data_storage_configuration block
• Create aws_bedrockagent_data_source with parsing_configuration
• Run terraform apply
• Upload and sync a document with multimodal data in Knowledge base
• Check the multimodal storage s3 bucket to check if data gets stored
