Error message
parse_failed
What it means
Raised by /parse-import's JSON branch when parse_import_from_text raises ValueError. That parser signals expected failures (unsupported content shape, undetectable table format, empty result) via ValueError, and its message is passed through as the 400 detail with error code parse_failed. The handler also logs text_bytes to correlate large inputs with failures.

Solutions
- Read the passthrough message — it states what the parser needed; adjust the pasted layout (e.g. include the header row) and retry.
- For tabular data, prefer the multipart file branch (upload the CSV/Excel directly) instead of pasting text.
- Trim unrelated prose so the input is mostly the code list/table.
Defensive patterns
Strategy: try-catch
Try / catch
resp = requests.post(f'{base}/api/v1/stocks/parse-import', json={'text': pasted}, timeout=30)
if resp.status_code == 400 and resp.json().get('detail', {}).get('error') == 'parse_failed':
msg = resp.json()['detail']['message']
if '格式' in msg or '无法识别' in msg:
suggestFileUpload() # guide user to upload the CSV/Excel instead
else:
showError(msg) Prevention
- Prefer uploading the original CSV/Excel file over pasting reformatted text.
- Include header rows when pasting tables so the parser can detect columns.
- Keep pasted content limited to the code list; strip surrounding prose.
When it happens
Trigger: Submitting free-form prose that contains no recognizable code columns; pasting a table whose header/delimiter layout the text parser rejects; text with only names but no codes and no resolvable symbols; extremely large clipboard text.
Common situations: Pasting from broker apps that use images-in-RichText (codes never arrive as text); mixed-language content the parser cannot segment; CSV pasted without headers; Excel cells pasted with tab alignment broken by reformatting.
