What it does

Apify Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Diagnose and fix common Apify Actor and API errors. Use when an Apify run fails, an API call returns 401/403/404/413/429, a proxy connection drops, an Actor build breaks, or a scrape hits an anti-bot block, and you need the cause plus a copy-paste fix. Trigger with "apify error", "fix apify", "actor failed", "apify not working", "debug apify", "apify 429".

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/error-reference.md`). Compatibility notes: Designed for Claude Code

It sits in Data & Analytics, covering Web scraping. It works with Apify. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • An Apify run fails
  • An API call returns 401/403/404/413/429
  • A proxy connection drops
  • An Actor build breaks

Example prompts

  • “apify error”
  • “fix apify”
  • “actor failed”
  • “/apify-common-errors”

Requirements

  • A credential in APIFY_TOKEN
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Bash(curl:*), Bash(apify:*), Bash(npm:*)

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Capture the exact error. Grab the Status / StatusMessage from the
  2. Match the signature. Find the matching entry in the table below, then

What it can do on your machine

Read from SKILL.md and the folder at commit 80f86df. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(curl:*)
    • Bash(apify:*)
    • Bash(npm:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl
    • jq
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.apify.com

    Also links to:

    • docs.apify.com
    • console.apify.com
    • status.apify.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • APIFY_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Apify Common Errors loads about 1.3k tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 497 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Apify Common Errors

Overview

Quick diagnostic reference for the most common Apify errors. Covers Actor run failures, API errors, proxy problems, anti-bot blocks, and platform-specific issues. The full per-error catalog — raw signature, cause, diagnosis, and copy-paste fix for all ten errors — lives in references/error-reference.md; this file is the lean triage path that points you there.

Prerequisites

  • An Apify API token exported as APIFY_TOKEN (Console > Settings > Integrations).
  • Access to the Apify Console for reading run and build logs.
  • curl and jq on PATH for the diagnostic commands below; apify CLI optional for build inspection.

Instructions

Work the failure from signal to fix:

  1. Capture the exact error. Grab the Status / StatusMessage from the run, or the ApifyApiError message and HTTP code from the API response. The raw string is the key you match on.
  2. Match the signature. Find the matching entry in the table below, then open references/error-reference.md at that number for the cause, diagnosis, and fix.
  3. Diagnose before changing code. For run failures, pull the log via the API or Console (see the FAILED entry). For auth/rate/payload errors, the HTTP code already tells you the class — see Error Handling.
  4. Apply the fix from the reference, re-run, and confirm with the diagnostic commands.
Error signature → reference
#ErrorSignature to match
1Actor run FAILEDStatus: FAILED / exited with code 1
2Actor run TIMED-OUTActor timed out after N seconds
3Rate limitedRate limit exceeded (429)
4UnauthorizedAuthentication required (401)
5Build failedBuild failed: npm ERR!
6Proxy connection failed502 Bad Gateway / Could not connect to proxy
7Anti-bot blockstatus 403 / Captcha detected
8Out of memoryJavaScript heap out of memory

10Actor not foundActor '…' not found (404)

Output

Working through this skill yields:

  • The identified error class (matched signature + the one of ten catalog entries).
  • The root cause and a copy-paste fix (config change, code edit, or token/proxy action).
  • A verification command whose output confirms the run recovered (status SUCCEEDED, valid username, etc.).

Error Handling

HTTP CodeMeaningRetryableAction
400Bad requestNoFix input/params
401UnauthorizedNoCheck token
403ForbiddenNoCheck permissions

408TimeoutYesRetry with backoff
413Payload too largeNoReduce batch size
429Rate limitedYesAuto-retried by client
500+Server errorYesAuto-retried by client

Examples

Diagnostic commands for the most common triage steps:

bash
# Check Apify platform status
curl -s https://api.apify.com/v2/health | jq '.'

# Verify your auth (fixes 401 diagnosis)
curl -s -H "Authorization: Bearer $APIFY_TOKEN" \
  https://api.apify.com/v2/users/me | jq '.data.username'

# Check installed package versions
npm list apify-client apify crawlee 2>/dev/null

# Get last run status (find why a run FAILED / TIMED-OUT)
curl -s -H "Authorization: Bearer $APIFY_TOKEN" \
  "https://api.apify.com/v2/acts/USER~ACTOR/runs?limit=1&desc=true" | \
  jq '.data.items[0] | {status, statusMessage, startedAt, finishedAt}'

For the worked fix behind each error — e.g. reading a run log to find a stack trace, batching dataset pushes under 9MB, or switching to residential proxies to clear a 403 — see the matching entry in references/error-reference.md.
