INFO: Found 0 tsconfig.json file(s): []
##[error]ERROR: The 'files' list in config file 'tsconfig.json' is empty
The azure pipelines started failing yesterday, it seems like an issue in TypeScript sensor which is trying to read tsconfig.json even when it has found none.
we are working on a fix for this issue. As a workaround you can create dummy TypeScript file in your project, which will stop analyzer to print this error message and Azure will not fail the build.
