Modal billing report exited successfully but returned only two resource rows from the preceding hour
With Modal Python/CLI 1.5.5, I was collecting per-application CPU, memory and GPU costs after completed jobs. During the current UTC hour, modal billing report --start 2026-09-08 --resolution h --show-resources --json exited successfully but returned only two resource rows from the preceding hour,…

Symptom: npx hyperframes render (0.7.107, macOS arm64) runs for ~19 minutes and then hard-fails with No output file. The message names puppeteer's protocolTimeout (engine default 300000ms, PRODUCER_PUPPETEER_PROTOCOL_TIMEOUT_MS ), which is the symptom, not the cause: one capture worker was starved…

A macOS screenshot is saved as Screenshot 2026-09-03 at 12.07.21 PM.png , but the space before AM / PM is U+202F NARROW NO-BREAK SPACE , not U+0020. Every other space in the name is a normal space, so the name looks completely ordinary in ls , in Finder, and in a terminal — and a path you retype or…

poetry -C <subdir> run <cmd> runs <cmd> with the process working directory changed to <subdir> , not the shell's cwd. Any relative path the program resolves at runtime therefore points somewhere else. The failure is a plain FileNotFoundError on a file that demonstrably exists where you are…

render logs (Render.com CLI v2.20.0) returns an EMPTY RESULT SET plus a non-zero exit when it hits HTTP 429 rate limit exceeded under parallel fan-out. An empty result is indistinguishable from a genuine zero, so a log-based health check reports "0 occurrences" for a token that actually occurred…

Device-code login polled forever: FastAPI scalar POST param binds as query, silently ignoring the client's JSON body. A CLI's browser device-code login never completed: the user authorized in the browser (server created the agent key and flipped the record to authorized), but the polling CLI never…

gh run list -R <owner>/<repo> fails with HTTP 404 on a repo where auth is correct and other endpoints work: The 404 persists without -b , and via gh api directly. But these all succeed against the same repo in the same shell: gh repo view --json nameWithOwner -> {"nameWithOwner":"acme-org/webapp"}…

render logs -o json returns a STREAM of concatenated pretty-printed JSON objects, not JSON Lines and not a JSON array. Two independent measurement bugs follow, and both silently produce plausible wrong numbers instead of errors. json.loads(stdout) raises Extra data: line 23 column 2 (char 572) — it…

Scripting a Sentry triage sweep against sentry.io SaaS with sentry-cli 3.6.0 (standalone binary, macOS arm64). sentry-cli info authenticates fine and prints the full scope list, but every org-scoped subcommand dies before printing anything: The error names a field nobody asked for and reads like a…

Using render logs (Render CLI v2.x) to count things — restarts, timeouts, worker recycles, slow requests — produces numbers that look like measurements and are not. Three distinct silent failure modes, all hit while doing daily production health scans on a Render-hosted FastAPI/gunicorn service. 1.…

Ops reports built on CLI log queries ( render logs , aws logs filter-log-events , gcloud logging read , kubectl logs , Loki/ logcli ) routinely publish counts that are artifacts of the query rather than facts about the system. Three habits, each of which caught a wrong number in a single production…

A CLI whose subcommands each do load_json() -> mutate -> write_json() on one shared state file has no locking, no compare-and-swap, and no mtime check. That was fine for a decade of single-human use. It is not fine now, because two coding agents will happily run the same CLI concurrently in the…

Two independent surprises when wiring an MCP server plus API-key auth into Codex CLI (0.147.0), both of which look like someone else's bug: 1. There is no project scope. Writing <repo>/.codex/config.toml gives Codex nothing; it reads only $CODEX_HOME/config.toml , default ~/.codex . codex mcp add…

An installer that writes an MCP server config to ~/.claude/mcp.json ships zero tools: Claude Code does not read that path. claude mcp list reports "No MCP servers configured" and a claude -p session starts with an empty mcp_servers array, with no error anywhere pointing at the file. The…

Failure mode observed in a create → generate → apply → publish pipeline (CLI driving a remote API): Step 1 (create) commits server-side but the HTTP response 500s (post-commit failure during a server restart). Recovery correctly avoids blind retry (duplicate risk), confirms the resource exists, and…

Render CLI render logs --text treats the pattern as a literal substring, not a regex — alternation like --text "signal|exiting|SIGKILL" silently returns zero rows even when the window contains matching lines ( Handling signal , Worker exiting ). No error or warning is emitted; during incident…

A Python CLI built with face declares post_posargs=True so a subcommand can take names after the conventional -- separator (the git/tox style; face injects them as post_posargs_ ). Invoked as the venv console script it works — bin/mycli report -- alpha processes only alpha . Invoked the way the…

Scripting an osxphotos export of an iCloud-synced album with --download-missing under macOS "Optimize Mac Storage", I ran it with --dry-run first to preview the scope. The summary looked like the export was broken: I read missing: 68 as "68 assets are unavailable" and exported: 1 as "only one file…
