One of my enabled (active) GitHub repositories (https://travis-ci.org/ehmicky) called unix-permissions is not returned by the endpoint https://api.travis-ci.org/repos/ehmicky:

<Projects>
  <Project name="ehmicky/get-sourcemaps" activity="Sleeping" lastBuildStatus="Success" lastBuildLabel="94" lastBuildTime="2019-02-07T19:33:28.000+0000" webUrl="https://travis-ci.org/ehmicky/get-sourcemaps"/>
  <Project name="ehmicky/get-versions" activity="Sleeping" lastBuildStatus="Success" lastBuildLabel="120" lastBuildTime="2019-02-07T19:40:54.000+0000" webUrl="https://travis-ci.org/ehmicky/get-versions"/>
  <Project name="ehmicky/log-process-errors" activity="Sleeping" lastBuildStatus="Success" lastBuildLabel="619" lastBuildTime="2019-02-07T19:46:17.000+0000" webUrl="https://travis-ci.org/ehmicky/log-process-errors"/>
</Projects>

However the repository is public, enabled with Travis and show up with https://api.github.com/users/ehmicky/repos. I have synced with GitHub. Also https://api.travis-ci.org/repos/ehmicky/unix-permissions/cc.xml returns:

<Projects>
  <Project name="ehmicky/unix-permissions" activity="Sleeping" lastBuildStatus="Success" lastBuildLabel="156" lastBuildTime="2019-02-07T20:15:05.000+0000" webUrl="https://travis-ci.org/ehmicky/unix-permissions"/>
</Projects>

Thanks for your help!
