Improve Error Handling on Transactions Requiring Multiple Payers

[0xhank]

I (a beginner in SVM and anchor) ran into issues debugging a transaction requiring multiple fee payers. Having verbose error messages would have helped me debug this issue far quicker.

When I didn't manually set the feePayer in the transaction object, I received an unclear error message:

the following line was required before sending the transaction:

transaction.sign(keypairs.tokenMintAccount);

The error you shared doesn't seem to be coming from Anchor. You can avoid manually setting the fee payer by using program.provider.send.
