Cypress throws error cy.task('copyTestDir') failed with the following error: > EPERM: operation not permitted, copyfile 'C:\Work\Vrest repos\vrest-meta-bkup\vrest-ng-meta\packages\vrest_ui\test\test-data-original' -> 'C:\Work\Vrest repos\vrest-meta-bkup\vrest-ng-meta\packages\vrest_ui\test\test-data'

[nsrivastava645]

I am trying to do a file system operation i.e., copy a directory which contains test data to another temporary directory. I am using fs-extra and doing that using cypress plugins mehod.
My plugin file looks like this
const fs = require('fs-extra'); const path = require('path'); import vAgent from '../../../vagent'; const source = path.join(__dirname, '..', '..', "test", "test-data-original"), destination = path.join(__dirname, '..', '..', "test", "test-data"); module.exports = (on, config) => { on('task', { copyTestDir() { return new Promise((resolve, reject) => { try { if (fs.existsSync(destination)) { fs.removeSync(destination); } fs.mkdirpSync(destination); fs.copyFileSync(source, destination); } catch (error) { reject(error); } resolve('files copied'); }) }, countFiles() { let files; try { files = fs.readdirSync(destination); } catch (err) { console.log(err); } return (destination); }, async readFileViaVagent(filePath) { let content = await vAgent.readFile(filePath, 'utf-8'); return content; } }) }

My testcase file looks like this:
describe('Test Suites Section', () => { it('Open Configuration tab', () => { u.openApp(cy, Cypress.env('isPro')); cy.task('copyTestDir'); cy.task('countFiles').then((fileCount) => { console.log(fileCount); }); u.addProject(cy); u.openConfigurationTab(cy); });

The error I am receiving is :
CypressError: cy.task('copyTestDir')` failed with the following error:
