Using a custom authority provider within eosjs for Greymass Fuel
Raw
authorityprovider.js
// A custom cosigner AuthorityProvider for EOSJS v2
// This provider overrides the checks on all keys,
// allowing a partially signed transaction to be
// broadcast to the API node.

const { transaction } = args;
// Iterate over the actions and authorizations
transaction.actions.forEach((action, ti) => {
action.authorization.forEach((auth, ai) => {
// If the authorization matches the expected cosigner
// then remove it from the transaction while checking
// for what public keys are required
if (
auth.actor === 'greymassfuel'
&& auth.permission === 'cosign'
) {
delete transaction.actions[ti].authorization.splice(ai, 1)
}
})

I'm not sure why that would be appearing without more details. If you could shoot an email over to [email protected] and let us know which page you were on and what action you were trying to perform when that error appeared, it'd help us track things down. Thanks!
