bedrock second knowledge base

All, i am trying to create second knowledge base based on pinecone db. The first one created without any problems. However, second one shows error The knowledge base storage configuration provided is invalid, please check your configuration. secret arn is the same. new role has been created. new s3 bucket has been used with the same configuration as the old one new index with proper url is created - i verified that this is accessible by python code. is it possible to have several knowledge based for the same provider? where can i find error details (log file)? thank you Yevgeniy
