Cannot install mitmproxy certificate on windows 10

In windows cmd, I switched to the folder where the certificate is present and ran this command:

certutil.exe -importpfx Root mitmproxy-ca-cert.p12

The output was:

Enter PFX password:
CertUtil: -importPFX command FAILED: 0x80070056 (WIN32: 86 ERROR_INVALID_PASSWORD)
CertUtil: The specified network password is not correct.

I had entered a random string of 1234 as my password and got the above error message. What I am doing wrong and how do I fix this problem ?

Thanks !

I got the answer from here Windows asks for p12 password when installing p12 key generated by openssl.

I used an empty password to resolve the problem. But, I don't know if this would have any negative consequences later.
