Clean DB with npx commands in Cypress - database

Question

I would like to clear the database of an application that I am testing using Cypress using npx commands, but when running the test I get the following error:
"Error: Cypress Error: cy.exec('npx sequelize db:migrate:undo:all') failed because the command exited with a non-zero code.
Pass {failOnNonZeroExit: false} to ignore exit code failures.
Information about the failure:
Code: 1
Stderr:
(node:20068) Warning: Setting the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0' makes TLS connections and HTTPS requests insecure by disabling certificate verification.
(Use `node --trac..."
I would like to clear the database of an application that I am testing using Cypress, I know that the commands are:
`Cypress.Commands.add("cleanDB", () => {
//cy.exec('set NODE_TLS_REJECT_UNAUTHORIZED=0')
cy.exec('npx sequelize db:migrate:undo:all')
cy.exec('npx sequelize db:migrate')
cy.exec('npx sequelize-cli db:seed:all')
//cy.exec('set NODE_TLS_REJECT_UNAUTHORIZED=1')
})`
to clear and run the migrations, I have already tried to change the error variable to 0, I ran Cypress as an administrator, used a .exec command parameter to run the command in the folder where the api is running but nothing works.
