UNSUPPORTED_OPERATION error

[Özün Çağan Altun]

When I run the code I get an error like this, after the error the code runs and detects new pairs. However, it does not buy. I could not find where the error was.

Error: cannot override "_hex","_isBigNumber","fromTwos","toTwos","abs","add","sub","div","mul","mod","pow","and","or","xor","mask","shl","shr","eq","lt","lte","gt","gte","isNegative","isZero","toNumber","toString","toHexString","toJSON" (operation="overrides", overrides=["_hex","_isBigNumber","fromTwos","toTwos","abs","add","sub","div","mul","mod","pow","and","or","xor","mask","shl","shr","eq","lt","lte","gt","gte","isNegative","isZero","toNumber","toString","toHexString","toJSON"], code=UNSUPPORTED_OPERATION, version=contracts/5.0.12)

Did you try to change gasPrice and gasLimit numbers?

Hi, i got the same error too, i've change the gas code as per this snippet. Please assist thanks.

Date.now() + 1000 * 60 * 10, // 10 minutes
    {
        gasPrice: '10000',
        gasLimit: '2000000'
    },
  )
  const receipt = await tx.wait()
