Sonar-scanner cli failing to analyze CSS

Gaspacchio · December 8, 2020, 1:36pm

I’m encountering errors when running the sonar-scanner. It appeared today and I haven’t found any topic discussing it yet.

Details:

runtime:
- SonarScanner 4.5.0.2216
- Java 11.0.6 AdoptOpenJDK (64-bit)
- Linux 4.19.78-coreos amd64
- Gitlab CI on gitlab.com

Error observed:

Hello @Gaspacchio,

which version of Node.JS is installed for the analysis?

The same for me, any ideas when it will be fixed or what is the root cause?

Experienced the same issue with Node js v14.17.0, v13 and v15 too…

Sergio_Morales · July 2, 2021, 4:00pm

Hi!

I have the same problem using the last docker image versions for both the server and the scanner.

It seems related to ts-node ERR_UNKNOWN_FILE_EXTENSION after adding "type": "module" to package.json · Issue #1171 · TypeStrong/ts-node · GitHub.

Anyone knows how to solve this?

FBNitro · July 16, 2021, 6:03pm

I can confirm this issue is a result of using ESModules, ie: setting “type”: “module” in package.json. The CSS Scanner is missing the file extension on an import and needs to be updated.

This is a blocking issue for me as I have a ton of scripts in module format, I am not going to convert it all to CommonJS because of SonarQube.

jblanco · August 23, 2021, 8:45pm

@saberduck Any update on this? I am getting the same error but don’t see a solution posted here.

I am using the local instance of SonarQube.

Thanks!

jblanco · August 24, 2021, 3:22pm

@Gaspacchio were you able to find a solution?

YuerLee · September 4, 2021, 7:00am

Related issue: sonar-css#366.

pubmikeb · October 11, 2021, 9:07pm

I have the same issue on Node.js v.17 EAP and the latest SonarQube/SonarScanner.

saberduck · November 12, 2021, 4:10pm

hello,

I was finally able to reproduce this problem. It seems that we accidentally pickup package.json from the analyzed project, and if this project is setting type:module in package.json it will fail to start CSS analysis.

To workaround this issue you can configure the scanner work dir to be located outside of the analyzed project using sonar.working.directory property.

This will be also fixed in the next release of SonarQube 9.2 and soon it will be deployed on SonarCloud (I expect next week).

Sorry, that this took so long to address, we were not able to reproduce the problem on our side until very recently.

saberduck · November 15, 2021, 8:54am

For reference, the fix was done in this PR Explicitly specify that we use commonjs modules by saberduck · Pull Request #2878 · SonarSource/SonarJS · GitHub, originally problem was located in sonar-css plugin, however, now CSS analysis is provided via sonar-javascript plugin.

This PR only makes usage of commonjs modules explicit, it was the case already implicitly, because commonjs is the default in Node.JS

AnWeber · November 29, 2022, 3:21pm

Error seems not to be fixed. I get this error using latest sonar scanner cli in docker (full log in zip)

sonartest.zip (22.1 KB)
add valid sonar-project,properties

Workaround is to remove “type” field in package.json

It seems to be the same issue mentioned from saberduck, but just in css-bundle package.
