Generated HTML reports are empty when running from CI

[tijnster]

Describe the bug
Hi!

When I am running my tests locally, then merging and marging my json to html files works fine (I do have to use the Bash terminal, as I am on windows, else I would run into json parsing errors).
However, when i try to do this from Gitlab CI it does generated an HTML report as an artifact, but it remains empty..

Code Reproduce
Yml file:
cypress-e2e:
image: cypress/base:10
stage: test
script:
- npm run cy:run:staging
- npx mochawesome-merge — reportDir mochawesome-report > mochawesome-report/output.json
- npx marge mochawesome-report/output.json
artifacts:
paths:
- mochawesome-report/output.html
expire_in: 1 week

Expected behavior
A fully loaded HTML file with content of the tests.

Screenshots

Environment (please complete the following information):

• Platform Linux
• mochawesome version 3.1.2
• mocha 5.2.0
• Node version 10.15.3

Additional context
Add any other context about the problem here.

Looks like the mocha versions since 6.0.0 has this issue

mocha version "5.2.0" works fine without any errors.

[adamgruber]

@sagaru I think you mean mocha since the latest version of mochawesome is 3.1.2. Either way, the issue you're describing sounds like #269.

@tijnster Can you provide a link to a repo where the issue can be reproduced?

[YOU54F]

@sagaru @adamgruber I've added up to date information about the fixes to work with Mocha 6 in #269 . I've now implemented it as a non-breaking change :) so it can be used with mocha versions 6+ and below

Hi everyone, It seems cleaning assets folder inside the report folder can resolve the issue. It won't regenerate the content of the asset if it already exists (Can't recognize the assets belongs to older versions of mochawesome or MARGE?!?!?!?).
I had a look into sources and probably the root of the issue is MARGE (Mochawesome-report-generator) ?!?!?!?!?!
