no coverage data available

Error message

no coverage data available

What it means

TeamCity coverage badge's `transform` extracts covered/total statistics from the TeamCity REST build statistics endpoint. When the statisticValue entries for the coverage counters are absent (undefined), it throws an InvalidResponse — not NotFound — with 'no coverage data available', meaning the build reported no coverage data at all.

Solutions

1. Enable code coverage in the TeamCity build configuration (e.g. IDEA coverage or JaCoCo agent) and re-run the build
2. Verify the buildId belongs to a successful, finished build that ran with coverage
3. Confirm the `server` param points to the right TeamCity instance and the build exists there
4. Inspect GET <server>/app/rest/builds/buildType:(id:<buildId>)/statistics to confirm coverage statistic keys exist

Example fix

// before
/badge/teamcity-coverage/MyBuildId?server=https://teamcity.example.com  // build has no coverage agent
// after: enable IDEA/JaCoCo coverage in the build config, re-run, then keep the same badge URL

const stats = await fetch(`${server}/app/rest/builds/buildType:(id:${buildId})/statistics`, { headers }).then(r => r.json());
const hasCoverage = (stats?.property || []).some(p => /coverage/i.test(p.name));
if (!hasCoverage) throw new Error('build ran without coverage instrumentation');

const hasCoverageStats = (json) => Array.isArray(json?.property) && json.property.some(p => /coverage/i.test(String(p.name)));

try {
  return await teamcityCoverage({ buildId, server });
} catch (err) {
  if (err message includes 'no coverage data available') {
    // render 'coverage unknown' badge; enable coverage in the build config
  } else throw err;
}

When it happens

Trigger: Calling /teamcity-coverage/<buildId> (against `server`, default https://teamcity.jetbrains.com) where the finished build's /app/rest/builds/<locator>/statistics contains no coverage-related statistic values — e.g. builds whose tests run without coverage instrumentation.

Common situations: Build configuration without Java code coverage enabled (no IDEA coverage/jacoco agent); buildId points at a personal/failed/canceled build that produced no statistics; wrong TeamCity server URL so statistics come back empty for the locator; coverage counters renamed/missing in newer TeamCity.
