Hi guys, never encountered that one before. Is it some versioning error? I’ll paste `fuelup show` at the end. I’m running fuel-core on 127.0.0.1:4000.

The error:

```auto
swapMachine.ts:504 Error: Unknown field "fuelBlockSpend" on type "Message".:

{"data":null,"errors":[{"message":"Unknown field \"fuelBlockSpend\" on type \"Message\".","locations":[{"line":29,"column":3}]}],"status":200,"headers":{"map":{"content-length":"129","content-type":"application/json"}}},"request":{"query":"query getResourcesToSpend($owner: Address!, $queryPerAsset: [SpendQueryElementInput!]!, $excludedIds: ExcludeInput) {\n resourcesToSpend(\n owner: $owner\n queryPerAsset: $queryPerAsset\n excludedIds: $excludedIds\n ) {\n ...coinFragment\n ...messageFragment\n }\n}\n\nfragment coinFragment on Coin {\n utxoId\n owner\n amount\n assetId\n maturity\n status\n blockCreated\n}\n\nfragment messageFragment on Message {\n amount\n sender\n recipient\n data\n nonce\n daHeight\n fuelBlockSpend\n}","variables":

```

Sorry for the terrible formatting.

This looks like a version mismatch. Can you share steps to reproduce?

Hi Sarah, Thank you for your reply. To me, it happened when cloning matt’s bumped swayswap branch and then deploying the contracts manually on localhost.

1. `pnpm install`
2. `pnpm services:run`
3. `forc deploy --node-url ` `http://127.0.0.1:4000/graphql` ` --gas-price 1`
4. `add contract_ids to .env`
5. `pnpm scripts:setup`
6. `pnpm contracts:init --init-pool`
7. `pnpm contracts:build`
8. `pnpm dev`

Hi Maurice,

I encountered this error on my machine a while back and it was bc of a version mismatch. I would double check that you are pulling the latest version of my branch. Then I would change your toolchain to beta-3 (this is what I am using rn) and double check that your versions are correct with `fuelup check`. Then I would try the following commands.  
`pnpm install`  
`pnpm build`  
`pnpm services:reset`  
It may also be useful to remove your pnpm.lock file before running pnpm install
