I have two functions I am running on Autotask, one works fine, then the same simple type of function throws this error after trying to run it:
cannot estimate gas; transaction may fail or may require manual gas limit (error={"reason":"cannot estimate gas; transaction may fail or may require manual gas limit","code":"UNPREDICTABLE_GAS_LIMIT","error":{"code":3,"data":"0x08c379a00000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000002843616e206f6e6c79206c6f636b20726f756e642077697468696e206275666665725365636f6e6473000000000000000000000000000000000000000000000000"},"method":"estimateGas","transaction":{"from":"0x3f063AC8E4B260E96c331526b89D2DAFf3F95233","to":"0xE205743C142188e72494b4cf21561E58E4C62Fde","data":"0xd9d55eac","accessList":null}}, tx={"data":"0xd9d55eac","to":{},"from":"0x3f063ac8e4b260e96c331526b89d2daff3f95233","gasLimit":{},"speed":"fast"}, code=UNPREDICTABLE_GAS_LIMIT, version=defender-relay-client)
I'm happy to share more details but I'm just using a simple task with no parameters, just a function that runs every 5 minutes.
Any help will be much appreciated.
Environment
Using the front-end web interface to write/deploy the function.
Avalanche Test Network Fuji
Node.js
Details
Keeps experiencing a failure with 'UNPREDICTABLE_GAS_LIMIT' after trying to run the genesisLockRound function on this contract: 0xE205743C142188e72494b4cf21561E58E4C62Fde
As a side note, I have tried setting the max gas limit as well, and it still fails to send the actual gas limit through the live transaction.
Code to reproduce
const ethers = require('ethers');
const ADDRESS = '0xE205743C142188e72494b4cf21561E58E4C62Fde'
