contract.filters.<eventName> not returning a correct ABI hash that matches

[basedwdev]

I am using Ethers to listen to a Swap event from UniswapV3Pool instance link to ABI

I took this ABI, put it into a json file, and import it into my code, then I do something like

contract = new ethers.Contract(constractAddress, UNISWAP_ROUTER_ABI_V3, ethProvider);

if I console.log(contract.filters.Swap()) the return value is something like

{
address: ,
topics: [
'0xd78ad95fa46c994b6551d0da85fc275fe613ce37657fb8d5e3d130840159d822'
]
}

note if you look at the topic0 hash from the etherscan for example, the hash for this topic is actually "0xc42079f94a6350d7e6235f29174924f928cc2ac818eb64fed8004e115fbcca67"

https://etherscan.io/address/0x11950d141ecb863f01007add7d1a342041227b58#events

now, if I create something like

myfilter = { address: testPairV3, topics: [ "0xc42079f94a6350d7e6235f29174924f928cc2ac818eb64fed8004e115fbcca67" ] }

and do contract.on(myfilter, ()....)

This will successfully filter things out. Why is the topic value incorrect with this ABI? why even put an ABI here if I just need this value?

Updated: when converting json into a string, depending on how you accomplish this, what happens is that this can become padded with extra spacing or characters like '\n'
