error_during_execution - no debugging information as to why

So I have a job that runs, and periodically fails with a mysterious "error_during_execution" result subtype.

    echo "$FULL_PROMPT" | npx @anthropic-ai/claude-code -p --verbose --output-format json --allowedTools "Bash(echo:*)" "Bash(find:*)" > "$TEMP_FILE"

the prompt is mostly the same between runs. and more importantly, the output shows that all todos completed successfully. i didn't include all of the output below, but every step worked. it's only at the very end, after all todos are complete, that it bombs with an error_during_execution subtype for the result. there's no other information to help troubleshoot what could be happening.

this is not consistent. i can run it again with the same input, and it works fine. and it's only about one out of every 10 runs that this error occurs.

i can't find a single instance of "error_during_execution" when i search for that string on google. i'm reporting this because i'd really just like to know what i can do to debug this myself. maybe i'm missing something will tell me why this sporadically fails?
