Elastic Beanstalk can not create environment without semver

Question

I'm trying to create a new Elastic Beanstalk environment but seeing an error relating a a missing versionn of semver:

Creating application version archive "app-a538-220504_144649322441".
ERROR: FileNotFoundError - [Errno 2] No such file or directory: './node_modules/babel-jest/node_modules/@jest/transform/node_modules/@babel/core/node_modules/.bin/semver'

The error appears since I've added an .ebignore file which includes node_modules (which is intended and should remain ignored):

.ebignore

# dependencies
   
node_modules/

# repository/project stuff

.idea/
.git/
.gitlab-ci.yml
README.md

# misc

.DS_Store

# debug

npm-debug.log*
yarn-debug.log*
yarn-error.log*

To me this makes no sense at all. Why should eb need a dependency from my node_modules folder for it's internal versioning.
