Cannot convert undefined or null to object and if i remove try catch block this is the error it shows ->

call revert exception [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (method="display(address)", data="0x", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.7.0)

From the error it sounds like its more related to display(address) but let us know if you need more assistance with the upload part! We have some React examples here as well as an Next.js Template you can spin up with npx create-pinata-app
