Amazon Textract: How to select 'Raw text' option

Question

We are trying integrate amazon Textract api in our node.js application. we are facing some issue, FeatureType parameter while processing image. we need to achieve the below option via api:

We are not finding the option in the AWS JavaScript SDK.

export type FeatureType = "TABLES"|"FORMS"|string;

I'm trying this code:

const params = {
            Document: {
                /* required */
                Bytes: Buffer.from(fileData)
            },
            FeatureTypes: [""] // here i'm facing issue, if i pass "TABLES"|"FORMS" it working
        };
        var textract = new AWS.Textract({
            region: awsConfig.awsRegion,
            accessKeyId: awsConfig.awsAccesskeyID,
            secretAccessKey: awsConfig.awsSecretAccessKey
        })
        textract.analyzeDocument(params, (err, data) => {
            console.log(err, data)
            if (err) {
                return resolve(err)
            } else {
                resolve(data)
            }
        })

Getting this error:

InvalidParameterType: Expected params.FeatureTypes[0] to be a string

If I pass "TABLES"|"FORMS" its working but I need Raw Text option.

Thanks in advance

You have been calling the analyzeDocument() function:

Analyzes an input document for relationships between detected items.

It returns various types of text:

'BlockType': 'KEY_VALUE_SET'|'PAGE'|'LINE'|'WORD'|'TABLE'|'CELL'|'SELECTION_ELEMENT',

The LINE and WORD blocks seem to match your requirements.

Alternatively, there is also a detectDocumentText() function:

Detects text in the input document. Amazon Textract can detect lines of text and the words that make up a line of text.
