I'm trying to make a static call, but i'm get an error run the code.
The funny are i can put BigInt(32), but its obvious there is no output correct

Code Snippet

const MAX_UINT128: BigNumber = BigNumber.from(2).pow(128).sub(1);
collect
.staticCall({
tokenId: PtokenId,
recipient: _addressAccount,
amount0Max: MAX_UINT128,
amount1Max: MAX_UINT128,
})

You cannot mix-and-match v5 and v6; it is a major version change and they are incompatible. There is no longer a BigNumber class and you should be using ES2020 BigInt in v6: MAX_UINT128 = (2n ** 128n) - 1n

[Cazs03]

That was the problem with the JS compiler.
I have made a change in the tsconfig.json file
"target": "ES2020",
run again npm install
snipe finally

const MAX_UoINT128 = 2n ** 128n - 1n;
in the promise -->

const formated = formatUnits(result[0], 18);

[ricmoo]

You can also use (1n << 128n) - 1n, which is likely slightly faster and doesn’t use the exponential operator (which is likely why you needed es2020).

[Cazs03]

Both need the change if the target has the value : tsconfig.json "target": "es5",
If it doesn't return the error -> BigInt literals are not available when targeting lower than ES2020.

But both snipes works with
"target": "ES2020",
"target": "esnext",

[ricmoo]

Oh! Makes sense, it’s still a grammar change. If you need es5-compatible syntax, (BigInt(1) << BigInt(128)) - BigInt(1). But I recommend using the modern literal syntax and making the changes you suggested to your tsconfig.
