Conversation
…bpalash#1798) Segments from transcription backend may arrive with null start/end timestamps during dictation. Calling .toFixed() on null crashes the app with 'null is not an object (evaluating e.end.toFixed)'. Add null checks that render '-' when start/end is unavailable.

Move the missing-timestamp placeholder into i18n.
Line 291 adds the user-visible '-' literal, which bypasses the frontend locale contract. Replace it with a translation key and add that key to all 21 locale files. As per coding guidelines and path instructions, list any locale files missing the key before merge.

Normalize null segment endpoints before response serialization.
When NeMoASRBackend handles fast capture with word_timestamps=False, it emits non-empty segments with end=None; transcribe_audio then rounds that endpoint and the derived duration, which can raise TypeError before CaptureWidget stores the response for Transcriptions.jsx. Normalize null endpoints in the producer and add a fail-before/pass-after endpoint-to-page regression test.

When this test renders the null timestamp cases, each fallback is embedded in a complete range such as – – – or 1.5s – –, so getByText('–') finds no exact match and fails the frontend test suite. Match the rendered range strings instead.

Mount the page and assert the rendered segment rows. The test never renders TranscriptionsPage, so screen.getByText('Partial transcription') fails at Line 82 before exercising the fallback. After mounting, screen.getByText('–') at Line 85 still does not match because each fallback is part of a combined timestamp string; assert the three segment rows or their complete timestamp text instead.

Hi @debpalash — this PR is mergeable (fix: guard null seg.start/end in .toFixed(), fixes #1798). All checks passing. Could you review when you have a moment? |
2 participants
Fixes #1798. Segments from the transcription backend may arrive with null
start/endtimestamps during dictation startup. Calling.toFixed()on null crashes the app withnull is not an object (evaluating 'e.end.toFixed').Added null checks that render
-when start/end is unavailable, preventing the crash while keeping the display consistent.Root cause:
loadTranscriptionsstores the transcription entry, and segments from the backend can havestart=null/end=nullwhen dictation is just starting. The rendering at line 291 assumed both were always numbers.The Transcriptions view now handles null
startorendtimestamps without calling.toFixed(). It displays the translatedtranscriptions.timestamp_unavailablefallback and adds this key to all 21 locale files. Regression tests cover missing start, end, or both timestamps; risk is low.
