Invalid API Response: The provider returned an empty or unparsable response

[Drjacky]

Cline (gpt 5.6) wanted to execute:

cd /Projects/my-sample || exit 1
printf '%s\n' '=== ACTIVE TEST RUN LOG ==='
grep -nE '65232f7a-2748-424e-83b3-a16e9b28905f|\[TestRunner\]|RunStarted|RunFinished|Test run' Logs/Editor.log | tail -n 180
printf '%s\n' '=== TEST ASSEMBLY TIMESTAMPS ==='
stat -f '%Sm %N' -t '%Y-%m-%d %H:%M:%S' \
  Library/ScriptAssemblies/my-sample.Gameplay.dll \
  Library/ScriptAssemblies/my-sample.ServerDomain.dll \
  Library/ScriptAssemblies/my-sample.ServerDomain.Tests.dll
printf '%s\n' '=== LATEST COMPILATION ERRORS ==='
tail -n 5000 Logs/Editor.log | grep -E 'error CS[0-9]+|Compilation errors detected|Scripts have compiler errors' | tail -n 100 || true
printf '%s\n' '=== TEST RUN STATE FILES ==='
find Library Temp -type f \( -iname '*test*result*' -o -iname '*test*run*' \) -mmin -10 -print 2>/dev/null | head -n 100

but got:

Invalid API Response: The provider returned an empty or unparsable response. This is a provider-side issue where the model failed to generate valid output or returned tool calls that Cline cannot process. Retrying the request may help resolve this issue.

Cline hit repeated tool call failures. Try guiding it with a new prompt.
