ERROR: Failed to merge reports - Mochawesome

Current behavior:

I’ve installed the Mochawesome reporter and all the needed plugins. Whenever I try to run a folder it keeps giving me an ERROR that Cypress failed to merge the reports. It looks like that the script does not create a file in the folder mocha.

It only creates a report.json in Mochareports.

this is a part of my package.json.

{
  "scripts": {
    "cypress:open": "npm install && cypress open",
    "cypress:open:local": "npm install && cypress open --env configFile=local",
    "cypress:open:dev": "npm install && cypress open --env configFile=dev",

    "clean:reports": "(if exist cypress\\reports (rmdir /S /Q cypress\\reports)) && mkdir cypress\\reports && mkdir cypress\\reports\\mocha  &&  mkdir cypress\\reports\\mochareports",
    "pretest": "npm run clean:reports",
    "scripts": "cypress run --spec cypress/integration/website/schooltrip/**/*",
    "combine-reports": "mochawesome-merge  cypress/reports/mocha/*.json > cypress/reports/report.json",
    "generate-report": "marge cypress/reports/mochareports/report.json -f report -o cypress/reports/mochareports",
    "posttest": "npm run combine-reports && npm run generate-report",
    "test": "npm run scripts || npm run posttest"

Desired behavior:

What cypress needs to do according to all online explanation is to create a file in the Mocha and Mochareports and merge these files in order to get an HTML report.

Error given after a run:

> @ posttest C:\Users\iessadeq\Desktop\*********l\******-cypress-tests-master
> npm run combine-reports && npm run generate-report


> @ combine-reports C:\Users\iessadeq\Desktop\***********\*****-cypress-tests-master
> mochawesome-merge  cypress/reports/mocha/*.json > cypress/reports/report.json

You can change the legacy command:

from: mochawesome-merge cypress/reports/mocha/*.json > cypress/reports/report.json

to: mochawesome-merge cypress/reports/mocha/*.json -o cypress/reports/report.json

Pattern StagingJsonReports/.jsons/*.json matched no report files

I have my tests running as

npx cypress run --browser chrome --headless --spec cypress/integration/uk/smoke/*.spec.js --env grepTags=@trynow --reporter-options reportDir=StagingJsonReports,reportFilename=StagingTests,html=false,json=true,overwrite=false

After the execution I have my json reports for each individual tests in the folder “StagingJsonReports”, but the execution fails saying StagingJsonReports/.jsons/*.json matched no report files. Is there a way to override this. Also my screenshots are getting copied from the default directory to the this custom report directory. Are there ways to override this.
