Below are errors related to Gas Manager.

Invalid Policy ID

Example error message:

{ code: -32602, message: '"Invalid Policy ID. Please ensure you're sending requests with the api key associated with the policy's app, and that the policy is active."' }

Solution

Gas manager policies can only be tied to one app and one chain. To resolve this issue:

• Use BOTH the policy ID and the API key associated with the app for which the Gas Manager policy is configured

  • Policies can only be configured for one chain at a time

• Ensure the policy is active

Team Sponsorship Limit Errors

Here is an example error message:

This transaction’s USD cost will put your team over your gas sponsorship Limit. To increase your limit, please upgrade your account, buy gas credits in your Gas Manager Dashboard: <https://dashboard.alchemy.com/gas-manager>, or reach out to [account-abstraction@alchemy.com](<mailto:account-abstraction@alchemy.com>).

Here is an example of our old error message:

This transaction’s cost will put the team over their MAX token limit for this network. To increase the limit, reach out on discord or [support@alchemy.com](<mailto:support@alchemy.com>).

What is this?

This error means that this userOp will cause you to hit exceed your sponsorship limit. This limit is determined by your Alchemy tier (see limits here) and checks against the sum of pending and mined User Operations.

• We offer free unlimited sponsorship on testnets

• Your usage will reset once your gas manager bill is paid at the end of the month

Why do pending UOs count towards my limit?

Any valid paymaster signature will count towards this limit as these signatures could be used for sponsorship.

• Paymaster signatures are valid for the policy expiry time defined on the policy itself.

• Setting your policy expiry too long could cause the number of valid signatures to pile up. Even if those user operations are rejected at the Bundler level on send user operation, the paymaster signature will continue to be valid and count towards your limit until the signature expires on-chain. There is no way to invalidate this signature once it has been granted.

Will I get alerted when I get close to this limit?

Yes! Billing admin on your team account will be emailed when you are at 50%, 75%, 90%, and 100% of your limit.

Solutions

1. Upgrade your Alchemy plan - see limits here

2. Purchase gas credits - in your gas manager dashboard you can purchase gas credits in USD to increase your limit. Check out a demo here.

   • These credits will be a one time non-refundable purchase and applied to your gas manager bill at the end of the month

   • Your limit will be the sum of your tier limit plus any unused purchased gas credits
