Getting exception after running "cdk synth"

[awspractise]

Hello Team
After running the command "cdk synth" We are getting the following exception. Please let us know what could be the issue.
FYI we are running the CDK on "Amazon Linux 2023" OS.

jsii.errors.JavaScriptError:
  Error: spawnSync docker ENOENT

The above exception was the direct cause of the following exception:
