BASE64Decoder: Error in encoded stream: Oracle Integration
While mapping the streamReference to opaque element in Oracle Integration you might get the “BASE64Decoder: Error in encoded stream: needed at least 2 valid base64 characters, but only got 0 before padding character (=), the 10 most recent characters were: “Sua1HdwQ==” the error.
Following is the complete error detail you may see in the error stack trace:
Error Summary: oracle.fabric.common.FabricInvocationException: oracle.soa.api.invocation.InvocationException: faultName: {{http://schemas.oracle.com/bpel/extension}runtimeFault}

,code=<code>java.lang.RuntimeException</code>
,detail=<detail>BASE64Decoder: Error in encoded stream: needed at least 2 valid base64 characters, but only got 0 before padding character (=), the 10 most recent characters were: "Sua1HdwQ=="</detail>}
cause: {BASE64Decoder: Error in encoded stream: needed at least 2 valid base64 characters, but only got 0 before padding character (=), the 10 most recent characters were: "Sua1HdwQ=="}
Issue: The issue is because you are trying to map the stringReference to an opaque element as is without doing converting it into the base64.
Solution: To solve this error, you need to use encodeReferenceToBase64 function in the mapper as shown in the following image:
After using this conversion, your integration will work like a charm.
