I have a Cypress project with TypeScript support using the Cucumber Preprocessor and all of a sudden it started to throw the below exception:
TypeError: Cannot read properties of undefined (reading 'uid')
Some times it works when I change to a different workspace but again this error is reproducing when I open the Cypress runner itself and even when executing in Jenkins too.
Cypress Runner: (v8.4.0)
Jenkins Console: (v8.7.0)
The function exported by the plugins file threw an error.
We invoked the function exported by `C:\Jenkins\workspace\ABC\cypress\plugins\index.js`, but it threw an error.
TypeError: Cannot read properties of undefined (reading 'uid')
