"What is the process for altering the Node.js version used with automatically generated custom resources?"

"Hello all,

I’m working with an AWS serverless application that includes multiple Python Lambdas. Whenever I execute ‘serverless deploy,’ in addition to the Python Lambda functions defined in the serverless.yml file, an extra Node.js Lambda called ‘<my_app_name>-prod-custom-resource-event-bridge’ is automatically generated, using Node.js 12.x as its runtime.

My question is: How can I modify the Node.js version for this Lambda?

Thank you in adv
