hey guys, i'm trying to understand how to use the uniswap function swapExactTokensForTokens, but when i try to add to the path parameter i keep getting this error

Invalid type for argument in function call. Invalid implicit conversion from address[2] memory to address[] memory requested

googling it hasn't brought up any solution. how can i solve this?

parameter input is address[]
i'm passing in [token0, token1]

yea i get that, but how else would i be able to pass in to the path parameter without creating an array of n size?

i see. so you create a typed dynamic array but create it to size 2, then insert into the array by index

would this be the only way?

yes exactly

it feels much like a workaround rather than a proper solution, but i've not worked with solidity for too long

for memory arrays that is the only way

if it's for an array in the storage, then you could do path.push()
