I’m trying to deploy a contract and I am running into the error:

Unknown fields “coinsToSpend” on type “Query” did you mean “resourcesToSpend”

How do I fix this?

this is due to a version mismatch. Please install and use the toolchain for beta-1 or beta-2 respectively.

You can do that following these instructions:

1. Make sure you are on the latest fuelup version with the following command: `fuelup self update`
2. Run the following command to install the toolchain: `fuelup toolchain install beta-1`

Check out the docs for `fuelup` here: [Introduction - fuelup](https://fuellabs.github.io/fuelup/v0.11.1/)
