Exclude flag no working with exclude-after-remap

Link to bug demonstration repository

I'm use complited cov.json that was generated by https://gitlab.com/gitlab-org/security-products/analyzers/fuzzers/jsfuzz

In my case I give many cov.json from different jobs of tool above. Every job are working into some docker. Then I merged reports from all dockers into one and tryed to build report into job of new docker with needed envirounment. I use option --exclude-after-remap=false becouse without it I get clear report. The same trouble as here: https://github.com/istanbuljs/nyc/issues/1172

My shell for build report:

nyc merge all_coverages merged-output/coverage.json
nyc report -t merged-output \
--report-dir merged-report \
--reporter=html --exclude-after-remap=false \
--exclude ["coverage/**","packages/*/test{,s}/**",\
"**/*.d.ts","test{,s}/**","test{,-*}.{js,cjs,mjs,ts}",\
"**/*{.,-}test.{js,cjs,mjs,ts}","**/__tests__/**",\
"**/{ava,nyc}.config.{js,cjs,mjs}","**/jest.config.{js,cjs,mjs,ts}",\
"**/{karma,rollup,webpack}.config.js","**/{babel.config,.eslintrc,.mocharc}.{js,cjs}",\
"dist/controllers/ldap/**","dist/controllers/sso/**",\
"dist/helpers/[data-encrypt-helper|license-helper].js",\
"tests/**","node_modules/kerberos/**","node_modules/babel*/**",\
"node_modules/bluebird/**","node_modules/ldap*/**",\
"node_modules/mockery/**","node_modules/tslib/**",\
"node_modules/mkdirp/**","node_modules/uuid/**"]

After it I see "tests/" for example and other custom excluded.

:

Expected Behavior

Can't exclude custom modules from report nyc.

Observed Behavior

Troubleshooting steps

• Get some 2 or more cov.json files
• Do merge them
• build report with options --exclude-after-remap=false and --exclude [test/**] (it's for my code)
• See that --exclude options is not working

I'm encountering the same problem, has anyone had a chance to look into this? I'm not even trying to exclude anything from my report.

I ran a cypress test with @cypress/code-coverage instrumentation which generated a .nyc_output/out.json file and attempted to generate the report with npx nyc report --reporter=text-summary and the output was empty. I have no other nyc configuration present.

If I add on the --exclude-after-remap=false, the summary shows actual results.

Any resolution to this issue?
