We are making this sniper bot https://github.com/Nafidinara/bot-pancakeswap , which only can swap WBNB (or MATIC or KCS, depends on the blockchain you select) for any token.

So we want to swap any tokens for any tokens.

Example: swap CAKE for WBTC

The function that you will find at this code is "swapETHforExactTokens". Now we are using "swapExactTokensforTokens" for swapping any token, and it runs well, but we get this error at the blockchain:

TRANSFER_FROM_FAILED

Do you know how to solve this?

Thanks!
