Cannot read property address of undefined

When I try to start index.js error I get this error:
C:\Users\elias\Downloads\Kobflish-FlashloanArbitrage\pancake-bakery-arbitrage-main\index.js:38
Flashswap.networks[process.env.NETWORKID].address
^

TypeError: Cannot read property 'address' of undefined

I already migrated the contract but it still dosen't work.
