Hello Duncan.
I confirm the stack overflow only occurs when running the SonarCloud analysis. When turning off the SonarCloud build steps (SonarCloudPrepare, SonarCloudAnalyze and SonarCloudPublish) the build succeeds.
The verbose log of the build step is very large, so I’ve uploaded it to OneDrive. Please let me know if this is fine with you, if you’d rather have me share it another way I will do so.
Thanks.
