   This issue might be a duplicate of existing issues. Please check:

   • Claude Sonnet 4.5 Throws "text content block must contain non-whitespace text" #3375: Same exact error message "text content block must contain non-whitespace text" when using Claude Sonnet 4.5, also makes OpenCode unusable after a few minutes
   • "AI_APICallError: Text content blocks must contain non-whitespace text" on /compact #1681: Same error when using /compact command, also mentions unusable terminal and need to restart session

   Feel free to ignore if none of these address your specific case.
