Generating A License Key occur Mistake

[GitHub-Stephen]

Develop Envirment: Mac Os M2 chipest
JDK: 1.8

Hi,

I follow the guide and generate a project successfully ! But when I start the step2 "Generating A License Key" , it makes some mistakes, the terminal responses below information :

{"consumerAmount":1,"consumerType":"User","holder":"CN=Unknown","issued":1709113790330,"issuer":"CN=Company Inc.","subject":"StarGazer 2020"}zsh: command not found: {consumerAmount:1,consumerType:User,holder:CN=Unknown,issued:1565085418292,issuer:CN=Company

it seems like the command consider the parameter {"consumerAmount":1,"consumerType":"User","holder":"CN=Unknown","issued":1709113790330,"issuer":"CN=Company Inc.","subject":"StarGazer 2020"}" as a command ,not a parameter.

Questions:

• did I input a mistake command?
• what should I prepared before Generating A License Key?
