Cannot read property 'data' of undefined

[Rajesh-Kodandam]

I'm working on cypress: 7.4.0

describe('verif', () => {
before (function() {
cy.fixture('example').then(function(data){
this.data = data;
});
});
It('valida', () => {
cy.log('');
});
})

Not sure the reason I have this error while trying to use the data from fixture "Cannot read property 'data' of undefined"

Your advice much appreciated.

If you what to use fixtures from before block, you must use function callback, not arrow function () => {} in the it block.

https://docs.cypress.io/api/commands/fixture#this-context

describe('verif', () => {
  before (function() {
    cy.fixture('example').then(function(data){
      this.data = data;
    });
  });
  It('valida', function () {
    cy.log('');
  });
})
