SOCKET TIMEOUT ERROR - Zoho Catalyst OCR

SOCKET TIMEOUT ERROR - Zoho Catalyst OCR

Hi guys,

I am getting a "SOCKET TIMEOUT ERROR" when trying to OCR files using Python & Zoho Catalyst OCR

It works for some requests so i know the code works, but when it is a longer scanned pdf for example, it times out.

I would really appreciate your help getting this fixed! The error is: Failed OCR request: {"status":"failure","data":{"message":"Request timed out. Try again","error_code":"SOCKET_TIMEOUT"}}

My code is:

from flask import Flask, request, jsonify
import os
import requests

app = Flask(__name__)

*Auth Token Removed*

@app.route('/')
def index():
    return 'Hello World!'

@app.route('/process_ocr', methods=['POST'])
def process_ocr():
    access_token = get_oauth_token()
    if not access_token:
        return jsonify({'message': 'Failed to authenticate with Zoho OAuth'}), 500

    # Hardcoded image link for testing
    image_link = "*Zoho Workdrive Link removed*?directDownload=true"
   
    # Download the image from the given link
    image_response = requests.get(image_link)
    if image_response.status_code != 200:
        return jsonify({'message': 'Failed to download image', 'status': image_response.status_code}), 500

    # Prepare the OCR API call
    ocr_headers = {
        'Authorization': f'Zoho-oauthtoken {access_token}'
    }
    ocr_files = {
        'image': ('image.pdf', image_response.content, 'application/pdf'),
        'language': (None, 'eng,spa')
    }
    try:
        ocr_response = requests.post(
            headers=ocr_headers,
            files=ocr_files,
            timeout=200  # Set timeout to 60 seconds
        )
    except requests.exceptions.Timeout:
        return jsonify({'message': 'OCR request timed out, please try again later'}), 504

    if ocr_response.status_code != 200:
        print("Failed OCR request:", ocr_response.text)
        return jsonify({'message': 'OCR request failed', 'status': ocr_response.status_code}), 500

    ocr_data = ocr_response.json()
    print("OCR Response:", ocr_data)
    ocr_text = ocr_data.get('data', {}).get('text', '')
   
    # Post the OCR text to the webhook
    webhook_url = '*Webhook URL Removed*'
    webhook_response = requests.post(webhook_url, json={'text': ocr_text})
   
    return jsonify({
        'message': 'OCR processing completed',
        'status': webhook_response.status_code,
        'OCR Text': ocr_text,
        'OCR Data': ocr_data  # Optionally include full OCR response for debugging
    })

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=int(os.getenv('X_ZOHO_CATALYST_LISTEN_PORT', 9000)), debug=True)
