This member cannot have an 'override' modifier because it is not declared in the base class 'BaseError'.

I catch an error during compilation. Do you have any idea what can be a reason and how to fix it ? Thank you.

Error: node_modules/permissionless/errors/estimateUserOperationGas.ts:13:14 - error TS4113: This member cannot have an 'override' modifier because it is not declared in the base class 'BaseError'.

13     override cause: BaseError
                ~~~~~

What is your target in tsconfig?

[denys5dev]

Initially "target": "es2022"

but looks like to fix it also need to add lib prop with

"lib": [
      "ES2022",
      "dom"
    ]

then it works fine
