Error: cannot estimate gas When I run `yarn runop`

[LI-YONG-QI]

Hello everyone! I try to run runop.ts script on localhost, but I got the error message

I found that the code caused the error const ret = await testCounter.justemit();

When I update the code to const ret = await testCounter.connect(etherSigner).justemit(); it work I guessed this error is related to aasigner, because testCounter is connect aasigner in runop script When I console.log(aasigner.address) is undefined

Can someone help me?
