InternalAWSSSOOIDC.InvalidGrant exception throw - can not access because of package visibility #2028
Description
Describe the bug
I'm trying to access a Bedrock API using an expired SSO Token.
As expected, the call fails.
It throws a InternalAWSSSOOIDC.InvalidGrantException, see
This structure is marked with package access.
It means I can not catch this exception or write a if error == test to check for this exception.
The exception should be wrapped into an exception that users can catch separately and inspect for custom behaviour.
InvalidGrantException(properties: InternalAWSSSOOIDC.InvalidGrantException.Properties(error: Optional("invalid_grant"), error_description: Optional("Invalid refresh token provided")), httpResponse:
Status Code: HTTP status code: 400
x-amzn-errortype: InvalidGrantException:http://internal.amazon.com/coral/com.amazonaws.sso.oidc/,

Content-Type: application/json,
x-amzn-requestid: a5c498a1-060e-46ed-a796-1609cbef4b47, message: nil, requestID: nil)
Expected Behavior
The thrown exception must be public
Current Behavior
The exception is thrown, but it's impossible to write code like
} else if let invalidGrantError = error as? InternalAWSSSOOIDCS.InvalidGrantException { // <-- Cannot find type 'InternalAWSSSOOIDCS' in scope
throw BedrockLibraryError.authenticationFailed(
"AWS SSO token expired: \(invalidGrantError ?? "")"
)
}
Reproduction Steps
Write a client app
Use SSO authentication
Wait for the SSO token to expire
Try again
Possible Solution
Wrap the error into a publicly facing error ?
