Error parsing YAML file.

Error message

Error parsing YAML file.

What it means

JobApplicationProfile parses a YAML string (resume/profile data) with yaml.safe_load in its constructor. If PyYAML raises a YAMLError (syntax problems: bad indentation, tabs, unclosed quotes), it is re-raised as ValueError('Error parsing YAML file.') with the original exception chained.

Solutions

1. Read the chained exception (__cause__) or the logged message: it includes PyYAML's line/column of the syntax error.
2. Validate the YAML with yaml.safe_load in isolation (or a linter like yamllint) before constructing the profile.
3. Fix indentation (spaces only, no tabs) and quoting in the YAML file.

Example fix

# before
profile = JobApplicationProfile(open('resume.yaml').read())  # tabs break it
# after
import yaml
text = open('resume.yaml').read()
yaml.safe_load(text)  # fail fast with line info
profile = JobApplicationProfile(text)

import yaml
text = open('resume.yaml', encoding='utf-8').read()
yaml.safe_load(text)  # raises YAMLError with line numbers BEFORE the constructor
profile = JobApplicationProfile(text)

try:
    profile = JobApplicationProfile(text)
except ValueError as e:
    if 'Error parsing YAML' in str(e):
        show_yaml_error(e.__cause__)  # PyYAML marks with line/col
    else:
        raise

When it happens

Trigger: Passing a malformed YAML string to JobApplicationProfile(yaml_str): tab indentation, missing colons/spaces, unbalanced quotes or brackets, or duplicate keys under strict parsing.

Common situations: Hand-editing resume.yaml and breaking indentation, generating YAML from templates with wrong whitespace, or Windows line-ending/tab issues from copy-paste.
