🌐 Project Name: Anonymous Feedback dApp

A full-stack decentralized application (dApp) built on the Stellar blockchain 🌟. This dApp allows users to submit anonymous feedback seamlessly. The smart contract assigns a unique ID to each feedback entry, which can later be accessed using its corresponding feedback ID.

⚠️ Current Issue:

🛑 Issue:

undefined when fetching data from the blockchain using Stellar-SDK.

⚙️ Working Functions:

Both send_feedback() and fetch_feedback() function correctly when invoked via Stellar-CLI.

🐛 Issue Details:

The fetch_feedback() function returns undefined when called via the fetchFeedback() interaction function using Stellar-SDK (located in src/components/Soroban.js).

Similarly, the sendFeedback() function correctly stores feedback on the blockchain but returns undefined instead of the expected feedback ID.
