fix(e2e): increase utf8StreamWorkflow test timeout to 120s

[karthikscale3]

Summary

• Bumps the utf8StreamWorkflow e2e test timeout from 60_000 to 120_000 ms to fix intermittent failures on the nitro workbench

Root cause

The test was added in #1852 with a 60s timeout, but occasionally fails when the 4th sequential step ('مرحبا بالعالم') is step_created but never step_started — meaning a Vercel Queue delivery is dropped and must be retried. A retry can take 30–60s, which exhausts the 60s budget.

This is infrastructure flakiness, not a code bug — the same test passes in most CI runs and the Arabic text is coincidental (it's just the 4th step). The convention for streaming workflow tests (readableStreamWorkflow, webhookWorkflow) is 120_000 ms, which gives enough headroom for one retry cycle.

Test plan

• CI passes on the nitro E2E job

Summary

• Bumps the utf8StreamWorkflow e2e test timeout from 60_000 to 120_000 ms to fix intermittent failures on the nitro workbench

Root cause

The test was added in #1852 with a 60s timeout, but occasionally fails when the 4th sequential step ('مرحبا بالعالم') is step_created but never step_started — meaning a Vercel Queue delivery is dropped and must be retried. A retry can take 30–60s, which exhausts the 60s budget.

This is infrastructure flakiness, not a code bug — the same test passes in most CI runs and the Arabic text is coincidental (it's just the 4th step). The convention for streaming workflow tests (readableStreamWorkflow, webhookWorkflow) is 120_000 ms, which gives enough headroom for one retry cycle.

Test plan

• CI passes on the nitro E2E job

Summary

• Bumps the utf8StreamWorkflow e2e test timeout from 60_000 to 120_000 ms to fix intermittent failures on the nitro workbench

Root cause

The test was added in #1852 with a 60s timeout, but occasionally fails when the 4th sequential step ('مرحبا بالعالم') is step_created but never step_started — meaning a Vercel Queue delivery is dropped and must be retried. A retry can take 30–60s, which exhausts the 60s budget.

This is infrastructure flakiness, not a code bug — the same test passes in most CI runs and the Arabic text is coincidental (it's just the 4th step). The convention for streaming workflow tests (readableStreamWorkflow, webhookWorkflow) is 120_000 ms, which gives enough headroom for one retry cycle.

Test plan

• CI passes on the nitro E2E job

Summary

• Bumps the utf8StreamWorkflow e2e test timeout from 60_000 to 120_000 ms to fix intermittent failures on the nitro workbench

Root cause

The test was added in #1852 with a 60s timeout, but occasionally fails when the 4th sequential step ('مرحبا بالعالم') is step_created but never step_started — meaning a Vercel Queue delivery is dropped and must be retried. A retry can take 30–60s, which exhausts the 60s budget.

This is infrastructure flakiness, not a code bug — the same test passes in most CI runs and the Arabic text is coincidental (it's just the 4th step). The convention for streaming workflow tests (readableStreamWorkflow, webhookWorkflow) is 120_000 ms, which gives enough headroom for one retry cycle.

Test plan

• CI passes on the nitro E2E job

Summary

• Bumps the utf8StreamWorkflow e2e test timeout from 60_000 to 120_000 ms to fix intermittent failures on the nitro workbench

Root cause

The test was added in #1852 with a 60s timeout, but occasionally fails when the 4th sequential step ('مرحبا بالعالم') is step_created but never step_started — meaning a Vercel Queue delivery is dropped and must be retried. A retry can take 30–60s, which exhausts the 60s budget.

This is infrastructure flakiness, not a code bug — the same test passes in most CI runs and the Arabic text is coincidental (it's just the 4th step). The convention for streaming workflow tests (readableStreamWorkflow, webhookWorkflow) is 120_000 ms, which gives enough headroom for one retry cycle.

Test plan

• CI passes on the nitro E2E job

Summary

• Bumps the utf8StreamWorkflow e2e test timeout from 60_000 to 120_000 ms to fix intermittent failures on the nitro workbench

Root cause

The test was added in #1852 with a 60s timeout, but occasionally fails when the 4th sequential step ('مرحبا بالعالم') is step_created but never step_started — meaning a Vercel Queue delivery is dropped and must be retried. A retry can take 30–60s, which exhausts the 60s budget.

This is infrastructure flakiness, not a code bug — the same test passes in most CI runs and the Arabic text is coincidental (it's just the 4th step). The convention for streaming workflow tests (readableStreamWorkflow, webhookWorkflow) is 120_000 ms, which gives enough headroom for one retry cycle.

Test plan

• CI passes on the nitro E2E job

Summary

• Bumps the utf8StreamWorkflow e2e test timeout from 60_000 to 120_000 ms to fix intermittent failures on the nitro workbench

Root cause

The test was added in #1852 with a 60s timeout, but occasionally fails when the 4th sequential step ('مرحبا بالعالم') is step_created but never step_started — meaning a Vercel Queue delivery is dropped and must be retried. A retry can take 30–60s, which exhausts the 60s budget.

This is infrastructure flakiness, not a code bug — the same test passes in most CI runs and the Arabic text is coincidental (it's just the 4th step). The convention for streaming workflow tests (readableStreamWorkflow, webhookWorkflow) is 120_000 ms, which gives enough headroom for one retry cycle.

Test plan

• CI passes on the nitro E2E job

Summary

• Bumps the utf8StreamWorkflow e2e test timeout from 60_000 to 120_000 ms to fix intermittent failures on the nitro workbench

Root cause

The test was added in #1852 with a 60s timeout, but occasionally fails when the 4th sequential step ('مرحبا بالعالم') is step_created but never step_started — meaning a Vercel Queue delivery is dropped and must be retried. A retry can take 30–60s, which exhausts the 60s budget.

This is infrastructure flakiness, not a code bug — the same test passes in most CI runs and the Arabic text is coincidental (it's just the 4th step). The convention for streaming workflow tests (readableStreamWorkflow, webhookWorkflow) is 120_000 ms, which gives enough headroom for one retry cycle.

Test plan

• CI passes on the nitro E2E job

• Overhead: Testbench overhead (Wall Time - Workflow Time)
• Samples: Number of benchmark iterations run
• vs Fastest: How much slower compared to the fastest configuration for this benchmark
