[!] Unable to read the license file `LICENSE` for the spec `CHIOTPField (0.1.0)`

[madanaya]

The dependency of CHIOTP was added to Podfile as below

pod 'CHIOTPField', '~> 0.1'

Though I am able to use library, I get this error when installing dependency

pod install
[!] Unable to read the license file `LICENSE` for the spec `CHIOTPField (0.1.0)`

I am currently using Xcode 11. Need some help resolving this warning
