sending a transaction requires a signer error

[Jorsche]

Hi all,
I am getting the error "sending a transaction requires a signer".
I am currently running on "ethers": "^5.4.7".

My getProviderDetails is a InfuraProvider as my current project is not passing in any wallet instance.
Appreciate your help in advance!

An InfuraProvider doesn’t have a Signer, so it cannot send transactions. You are probably trying to call a non-constant method on a Contract, which you cannot do without a Signer…

Appreciate your reply @ricmoo .
Can confirm that the only way is to create a wallet instance ? but currently the only data that i had from the biz team is the wallet address of a particular personnel. is there any way that i can get signer?

You can use any Signer. Wallet is an example that is backed by a private key. Other common Signers are things like MetaMask in a web browser or a managed private key in Geth/Clef.

But you need some way to pay for a transaction, in order to send a transaction. You can always use read-only calls for free.
