viem compile error, no direct calling of the functions, no typescript errors

[BrennerSpear]

when I run npm run compile (which just runs tsc), I'm getting 6 errors like this:

node_modules/viem/_types/utils/formatters/transaction.d.ts:26:1502 - error TS2536: Type 'K_2' cannot be used to index type '{ [K_3 in keyof TransactionEIP2930<bigint, number, boolean, "eip2930"> as K_3 extends keyof TOverrideReturnType ? TOverrideReturnType[K_3] extends void ? never : K_3 : K_3]: K_3 extends keyof TOverrideReturnType ? TOverrideReturnType[K_3] : TransactionEIP2930<...>[K_3]; } & TOverrideReturnType'.

index.ts (the only typescript file)

import functions from '@google-cloud/functions-framework';

import {createPublicClient, http, getFunctionSelector} from 'viem';
import {mainnet} from 'viem/chains';

...

Any ideas?

Do you have a minimal reproducible example I can take a look at?

[BrennerSpear]

Shared a repo with you!

For now in your TS file set skipLibCheck to true

[pepoospina]

I just had to still set skipLibCheck to true. Just in case.
