callstatic error with swapExactTokensForETHSupportingFeeOnTransferTokens

[Jeremy-DX]

I try to use callStatic with function swapExactTokensForETHSupportingFeeOnTransferTokens but not work.It shows CALL_EXCEPTION.

const res = await router.callStatic.swapExactTokensForETHSupportingFeeOnTransferTokens(
     [amountIn, amountOutMin, path, wallet.address, Date.now() + 1000 * 60],
      {
        gasPrice: Gas_Price,
        gasLimit: Trade_Config.gasLimit,
      }
    );

const res = await router.callStatic.swapExactTokensForETHSupportingFeeOnTransferTokens(
     [amountIn, amountOutMin, path, wallet.address, Date.now() + 1000 * 60]
    );

when I try to use callStatic with function swapExactTokensForTokens it works

const res = await router.callStatic.swapExactTokensForTokens(
     [amountIn, amountOutMin, path, wallet.address, Date.now() + 1000 * 60],
      {
        gasPrice: Gas_Price,
        gasLimit: Trade_Config.gasLimit,
      }
    );

Also I use the same parameter to make a real swap in pancakeswap, it works.

const res = await router.swapExactTokensForETHSupportingFeeOnTransferTokens(
     [amountIn, amountOutMin, path, wallet.address, Date.now() + 1000 * 60],
      {
        gasPrice: Gas_Price,
        gasLimit: Trade_Config.gasLimit,
      }
    );

why does this happened?

It depends on the implementation of swapExactTokensForETHSupportingFeeOnTransferTokens. Do you have any reference link to it?
