The MCP console formatter printed Playwright's zero-based ConsoleMessage.location().lineNumber unchanged, pointing readers one line before the source.

Convert the displayed line to one-based output in the shared formatter, preserving the existing URL:line format. Extend the existing console-message test to check inline and external script locations.

The regression fails without the fix in Chrome, Chromium, Firefox and WebKit. With the fix, all 168 console and neighboring CLI devtools tests pass across those projects; build and flint pass.

Fixes microsoft/playwright-mcp#1839

Hi, I'm the Playwright bot. I started to address the review comments on Linux: agent run

Hi, I'm the Playwright bot. I fixed the failing debug-output expectation.

The test_debug w/ console_messages test still expected zero-based :1; it now expects one-based :2. All 268 console, CLI devtools and test-tool checks pass on headless Chrome, Chromium, Firefox and WebKit on Linux. Build and flint pass. The original console regression still fails without the source fix on all four projects; macOS, Windows and headed runs were not checked.

🟢 The remaining failure is a confirmed pre-existing flake

Hi, I'm the Playwright bot. I checked the latest MCP report for 1099486f against the PR diff and refreshed CI history.

Details

The latest report has one failure. It is not likely caused by this PR. The earlier seven test_debug w/ console_messages failures are fixed: that test now passes in all seven MCP jobs.

Pre-existing flake

[chromium] › mcp/webmcp-dynamic.spec.ts:189 › a tool registered in an iframe can be called after the page is reloaded — on Linux, the second call returns Tool "webmcp_add" not found instead of "text": "5" (current job).

The exact same test and Chromium/Linux job failed with the same second-call mismatch on November 2, before this PR existed: #43864, SHA 660b627e (run). In the refreshed database, this test failed in 11 of 745 workflow run attempts outside this PR, and passed in the other 734, from October 12 through November 6.

The PR changes console source-line formatting and the matching console/debug expectations. It does not change iframe tool registration or collection, which this failure exercises.
