unable to create a document with raw content on dialog flow knowledge bases - google-cloud-platform

Question

i am using com.google.cloud.dialogflow.v2beta1.Document to create document through java rpc,we have a setContent() method which is used creating document with raw content, when i try to create document i am getting below exception.
Caused by: com.google.api.gax.rpc.InvalidArgumentException: Operation
with name
"projects/agent-fa5be/operations/ks-add_document-NDQ0NDQ3MjI5MDA3NTIxMzgyNA"
failed with status = GrpcStatusCode{transportCode=INVALID_ARGUMENT}
and message = CSV documents must have exactly two columns. The
provided document has 1 columns.
when i check dialogflow.v2beta1 Documentation there clearly mentioned content is deprecated use raw_content instead of content. but there is no supported method for raw_content in com.google.cloud.dialogflow.v2beta1.Document

Answer 1

I was experimenting a similar issue. I tried different libraries and techniques until I found something that worked. In my case I've to parse each row as follows:
let input = ['Question1', 'Answer1\n'];
let input2 = ['Question2', 'Answer2\n'];
let base64data = input.toString('base64') + input2.toString('base64');
const request = {
parent: 'projects/PROJECT_ID/knowledgeBases/KNOWLEDGEBASE_ID',
document: {
knowledgeTypes: ['FAQ'],
displayName: 'Echele',
content: base64data,
source: 'rawContent',
mimeType: 'text/csv',
},
};
This allowed my to submit the document, hope it works for you too!

Please find working solution
String documentName="test.csv";
try {
byte[] bytedata = filedata.toString().getBytes();
ByteString bytestring = ByteString.copyFrom(bytedata);
byte[] bytedata1 = "text/csv".getBytes();
ByteString mimestring = ByteString.copyFrom(bytedata1);
DocumentsSettings docuemtnSettings = DocumentsSettings.newBuilder()
.setCredentialsProvider(FixedCredentialsProvider.create(credentials)).build();
DocumentsClient documentsClient = DocumentsClient.create(docuemtnSettings);
Document document = Document.newBuilder().setDisplayName(documentName).setContentBytes(bytestring)
.setMimeTypeBytes(mimestring).addKnowledgeTypes(KnowledgeType.FAQ).build();
CreateDocumentRequest createDocumentRequest = CreateDocumentRequest.newBuilder().setDocument(document)
.setParent(knowledgeBaseName).build();
OperationFuture<Document, KnowledgeOperationMetadata> response = documentsClient
.createDocumentAsync(createDocumentRequest);
Document createdDocument = response.get();
System.out.format(" - docuemnt created ID: %s\n", createdDocument.getName());
