Error parsing YAML file.

Error message

Error parsing YAML file.

What it means

Raised by Resume.__init__ when yaml.safe_load (or subsequent pre-processing and super().__init__) raises yaml.YAMLError — i.e. the resume file's YAML text is syntactically invalid. The ValueError replaces the parser error, with the PyYAML exception (including line/column markers) attached as __cause__. Note the try block also covers exam-format normalization and the parent constructor, so a YAMLError raised anywhere in it lands here.

Solutions

1. Open the chained yaml.YAMLError (__cause__) — PyYAML reports the exact line and column of the syntax error.
2. Paste the file into a YAML linter (yamllint file.yaml) and fix flagged indentation/quoting issues.
3. Quote scalar values containing colons or special characters; replace tabs with spaces.
4. If the file may be empty or non-YAML, check content before calling Resume(file_path).

Example fix

# before
resume = Resume('resume.yaml')  # raises ValueError: Error parsing YAML file.

# after
import yaml
try:
    resume = Resume('resume.yaml')
except ValueError as e:
    if isinstance(e.__cause__, yaml.YAMLError):
        print(f"YAML syntax error: {e.__cause__}")  # includes line/column
    raise

import yaml
with open(path) as f:
    yaml.safe_load(f)  # dry-run parse; raises YAMLError with line/col before Resume()

import yaml
try:
    resume = Resume(path)
except ValueError as e:
    if isinstance(e.__cause__, yaml.YAMLError):
        show_yaml_error(e.__cause__)  # has problem_mark line/column
    raise

When it happens

Trigger: Loading a resume file with bad YAML: tabs used for indentation, unclosed quotes/brackets, duplicate keys (with strict loaders), colons missing after keys, or an empty file that later code paths treat as None.

Common situations: Hand-edited resume YAML breaking indentation; files with Windows line endings/encoding issues; YAML with date-like strings parsed into objects the constructor can't consume; truncated files from failed downloads or LLM output.
