Hi Toby,

This issue typically arises when a necessary dependency is missing during test execution. When running Cypress tests on LambdaTest, the dependency is retrieved from the npm_dependency object.

You have two options: either include all required dependencies (matching your package.json) in the npm_dependency object or remove the npm_dependency object entirely. In the latter case, LambdaTest’s Cypress CLI will fetch the dependency from package.json.
