Lethargy and continous 408 errors #307901
Description
Type: Bug
To add to this issue I'm experiencing the same problem but on MacOS, I'm sure there's a bunch of stuff I can trace but this problem was not present until the most recent update of VS Code.
My perspective is that something changed a lot in the past 30 days which is a barrier to work. If this continues I will seek to use alternative tools in VS Code, notably Claude code, because this is now a productivity sync.

Commentary on this morning's session:
April 5, 2026
Copilot continues to run slowly and also fail almost with every other chat. I’ve updated the extension to the latest version as of this morning. The following are the chronicles of the errors:
Attempt 1: Attempting to run a shell script that tests a discord connection
Prompt:
There are no posts with message marker discord-manual-1775392320
Error:
Sorry, your request failed. Please try again.

GH Request Id: F943:398CB1:13D0B6D:1B0C12B:69D256FF
Reason: Request Failed: 408 {"error":{"message":"Timed out reading request body. Try again, or use a smaller request size.","code":"user_request_timeout"}}
Retry attempt: Pressed try gain button
Initial response:
I’ll quickly isolate whether this is a webhook delivery issue or app-side issue by testing the Discord webhook directly and then re-running the manual flow with a fresh marker.
set -a && source .env && set +a && MARKER="discord-direct-$(date +%s)" && HTTP_CODE=$(curl -sS -o /tmp/discord_webhook_smoke.json -w "%{http_code}" -H "Content-Type: application/json" -d "{"content":"Vault direct webhook smoke test marker=${MARKER}"}" "$DISCORD_CONTACT_WEBHOOK_URL") && echo "marker=${MARKER}" && echo "http_code=${HTTP_CODE}" && echo "response_body=$(cat /tmp/discord_webhook_smoke.json)"

Reason: Request Failed: 408 {"error":{"message":"Timed out reading request body. Try again, or use a smaller request size.","code":"user_request_timeout"}}
Attempt 2: Now trying with new chat session
Prompt:
We are trying to verify that #file:07_discord_contact_happy_path.sh script actually works. We've tried to run it once and nothing was posted to discord. Note to run this you will need to set DEV_BOOTSTRAP_API_KEY and also pickup DISCORD_CONTACT_WEBHOOK_URL. I am concerned that the script doesn't actually pickup the webhook
Response Commentary:
Now the progress is partially better but still the same failures were experienced thrice. Subjectively, things are slow and the adding of these errors slows things down and I’d assume consumes more tokens.
