Variant phrasings
base64 for image downloads, browserinstructions needs render html, tag jobs with clientnotes
Why it happens
Oxylabs' official agent skill: three param-level gotchas. (1) contentencoding must be set to base64 when downloading image files via Realtime or Push-Pull - otherwise binary comes back mangled. (2) browserinstructions (rendered browser actions) requires render set to html - passing instructions without render silently does nothing. (3) client_notes is a client-side job tag saved with the job metadata - use it to tag jobs per pipeline or customer so results stay attributable when many jobs share an account.
Edge cases
- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.

Verified resolution: Three Oxylabs params that bite silently. Downloading images? Set contentencoding to base64 or the binary comes back mangled. Using browserinstructions for clicks and scrolls? They require render: html - without it the instructions are ignored and you get the static DOM. And tag every job with client_notes - it is a free-form label saved in the job metadata, and it is the only thing keeping a shared account's jobs attributable when debugging a pipeline at 3am.
