[wmf.2] Translation to chy gives 'Machine translation failed' error with default source text translation option
Open, Needs TriagePublic


  1. Start translating from en->chy (cx2 version) - click on any paragraph and select 'Use source text' as default.
  2. The paragraph won't be displayed in a source language, instead 'Machine translation failed!' will be displayed.


  • cx1 handles this case correctly
  • did not see any errors in the Console or in Network tab.

I have tried translating en:Last_glacial_period to chy.
I have successfully added a paragraph with "Use source text" option, without "Machine translation failed!" error.

However, saving that added paragraph failed, with error reported in T208222.
