Hi, I' m tring to deploy Uniswap V3 subgraph to a local graph node that is connected to a local ethereum node on the goerli network.

The OS is xubuntu v21.10 . The node is hyperledger besu v22.1.2. The graph-node version is 0.26.0 and run with docker-compose .

In the subgraph.yaml i have removed this: graft: base: block:

Because i haven't this subgraph deployed local, i changed the network to goerli and the start block to '7011478'. For the deploy I use these commands:

yarn codegen
yarn create-local
yarn deploy-local

After deployment and after some blocks have been indexed I get this error:


 Handler skipped due to execution failure, error: Mapping aborted at ~**lib/@graphprotocol/graph-ts/index.ts**, line 811, column 4, with message: **Value is not a BigInt**. wasm backtrace:        0: 0x25f8 - <unknown>!**src/types/schema/Token#get:decimals**       1: 0x2611 - <unknown>!~**lib/@graphprotocol/graph-ts/index/BigDecimal#constructor**     2: 0x29e3 - <unknown>!src/mappings/

QmNwsfk3kJi8zzmBDVEiCGqioRnpyZM1iSTPPVYVNyDsop, component: SubgraphInstanceManager

Does anyone have any idea what it could be?

  • It looks like you are trying to deploy a Uniswap V3 Subgraph , can you please show the subgraph yaml file ? and reveal more details in which chain(layer) you trying to deploy subgraph.

    Hi, I tried to deploy it on the goerli testnet. I downloaded the subgraph from github, the subgraph.yaml is this: github.com/Uniswap/v3-subgraph/blob/main/subgraph.yaml . I removed the lines 6, 7, 8: #graft: # base: QmPrb5mvZj3ycUugZgwLWCvK93jfXfhvfjRXrFk4tRmyCX # block: 14292820 I changed the network from 'mainnet' to 'goerli' , and the startBlock to 7011478 If you need more details just let me know. Thank you for your support
