Facing Error: Assembly "@custom-cdk-constructs/base-pipeline" not found

Currently we are exploring a way to generate documentation for our custom CDK construct.

We have created custom CDK contruct using following command
`npx cdk init lib --language=typescript`

and we tried to execute
`npx jsii-docgen`

And we faced following issue any help over here will be great.

Do we need to do anything additional on our newly created construct apart from executing `npx jsii-docgen`

Start with the npx jsii-docgen invocation and trace the reported failure through jsii-reflect/lib/type-system.js, jsii-docgen/lib/docgen/view/documentation.js, and lib/cli.js. Determine what setup or input is required for the custom assembly, then document the required steps or make the command handle this case; done means the reported construct can be processed without the assembly-not-found error.
