Describe the bug

Devika AI hanging

How To Reproduce

Steps to reproduce the behavior (example):

1. MacOS Version 14.6.1 (23G93)
2. "create a solution to accept URL from the user and generate a QR Code and provide the user the option to save the QR Code Image file"
3. Generates the plan and stops executing beyond that with a message "I am browsing the web to research the following queries"

Expected behavior

Should Continue to browse the web and beyond

plan :: ```
Project Name: QR Code Generator

Your Reply to the Human Prompter: I'd be happy to create a plan to generate a QR code from a user-provided URL and allow the user to save the QR code image. Let me outline the steps to accomplish this task.

Current Focus: Develop a web-based application that can generate a QR code from a user-provided URL and provide the option to save the QR code image.

Plan:

• Step 1: Research and select a suitable QR code generation library or API that can be integrated into the web application.
• Step 2: Create a simple web interface with an input field for the user to enter the URL and a button to generate the QR code.
• Step 3: Implement the QR code generation functionality using the selected library or API, passing the user-provided URL as the input.
• Step 4: Display the generated QR code image on the web page.
• Step 5: Implement a "Save" button or link that allows the user to download the QR code image to their local device.

Summary: This plan outlines the necessary steps to create a web-based QR code generator that can accept a URL from the user, generate the corresponding QR code, and provide the user with the option to save the QR code image. The key considerations are selecting a reliable QR code generation library or API, designing a user-friendly interface, and ensuring the save functionality works seamlessly. With these steps, the user should be able to easily generate and save QR codes for their desired URLs.
