Challenges Faced During Development

1. IPFS Upload Issues

One of the significant hurdles I encountered was related to uploading files to IPFS via Pinata. Initially, the file upload function would throw errors, leading to confusion about the request format.

Solution:

• I ensured that the headers and payloads were correctly formatted, particularly the content type. After troubleshooting and examining the API documentation thoroughly, I adjusted the headers and properly utilized the

  FormData

  object to manage file uploads. Implementing detailed error logging also helped pinpoint issues quickly.

2. Gas Limit Estimation

During the deployment and minting processes, I faced gas estimation errors which indicated that the transaction required more gas than allowed. This led to unsuccessful transactions and frustration while testing.

Solution:

• I researched the gas requirements for my smart contract functions, especially for the minting function. By setting a higher gas limit manually, I could successfully execute the transactions. Additionally, I implemented more robust gas estimation by dynamically adjusting the gas limit based on previous transaction costs.

3. TypeScript Type Issues

As the project utilized TypeScript, there were instances where TypeScript errors arose, particularly with type incompatibilities when interacting with Ethers.js.

Solution:

• To overcome this, I made sure to define clear types for my variables and state management. Leveraging TypeScript's strong typing allowed me to catch issues early. I also consulted the Ethers.js documentation for accurate type definitions and examples, ensuring proper type management across my codebase.
