fix: resolve runtime errors in 7 artifact parsers

[FrancoMorales1]

Summary

This PR fixes runtime errors that caused 7 artifact parsers to crash when processing an Android 13 image. Each fix is confined to changes within the affected artifact file. All fixes were verified by running the full ALEAPP pipeline against a real Android 13 extraction before and after the patch.

Changes per artifact

scripts/artifacts/wifiConfigstore2.py

Error: UnboundLocalError: cannot access local variable 'configcombined' + KeyError: 'name'

The *combined variables were assigned inside if datafieldname == '...' blocks but read after the inner loop, so any network entry missing a field (e.g. no ConfigKey) left the variable unbound. A second issue caused a KeyError when iterating child elements of WifiConfiguration that lack a name attribute (e.g. ).

Fix: Initialize all *combined variables to '' before the for b in a: loop so every network entry has defaults regardless of which fields are present. Switch c.attrib['name'] to c.attrib.get('name') and continue when the attribute is absent.

scripts/artifacts/deviceHealthServices_Battery.py

Error (Turbo_Battery): NameError: name 'time_offset' is not defined
Error (Turbo_Bluetooth): NameError: name 'file_found' is not defined

Turbo_Battery referenced an undefined time_offset variable instead of using the timezone column already present in the query result. Turbo_Bluetooth was missing the for file_found in files_found: iteration loop entirely, and had the same time_offset issue using the time_zone column.

Fix: Replace time_offset with row[4] (Turbo_Battery) and row[5] (Turbo_Bluetooth). Add the missing iteration loop in Turbo_Bluetooth and use os.path.basename for the source path to match the pattern used in the sibling function.

scripts/artifacts/FCMQueuedMessagesSkype.py

Error: json.decoder.JSONDecodeError: Unterminated string starting at: line 1 column 1654

json.loads(rec.key_values["rawPayload"]) raised an unhandled exception for records with truncated or corrupted JSON payloads, aborting processing of all subsequent messages.

Fix: Wrap the json.loads call in a try/except json.JSONDecodeError block and continue to skip malformed records while processing the rest.

scripts/artifacts/airGuard.py

Error: ValueError: time data '2022-08-18 17:26' does not match format '%Y-%m-%d %H:%M:%S'

The scan table stores timestamps without seconds (HH:MM), but convert_ts_human_to_utc strictly expects HH:MM:SS.

Fix: Before calling convert_ts_human_to_utc, check if the timestamp has only two colon-separated parts and append :00 if so.

scripts/artifacts/keepNotes.py

Error: sqlite3.OperationalError: no such table: text_search_note_content_content

The query joins against text_search_note_content_content, a full-text-search virtual table that is absent in some versions of the Google Keep database schema.

Fix: Wrap the cursor.execute call in a try/except sqlite3.OperationalError block that logs a descriptive message and continues to the next file instead of raising an unhandled exception.

scripts/artifacts/googleInitiatedNav.py

Error: TypeError: list indices must be integers or slices, not str

When the protobuf contains multiple navigation entries, blackboxprotobuf decodes values['1'] as a list; when there is only one entry it returns a dict. The original code used isinstance(values, dict) (always True) instead of checking the inner value, so the single-entry path was always taken and failed on the list case.

Fix: Retrieve values.get('1', []), wrap a bare dict in a list, and iterate uniformly over the resulting list.

scripts/artifacts/googleVoice.py

Error: AttributeError: 'dict' object has no attribute 'decode'

Field '10' of the decoded message protobuf holds the message text as bytes in older layouts, but as a nested dict in newer ones. The code unconditionally called .decode('utf-8').

Fix: Check isinstance(raw, bytes) first; if it is a dict instead, extract the first bytes value found within it (falling back to str(raw) if none is present).

Notes

This is one of my first open source contributions — I would really appreciate any feedback or corrections if something is not right. I received assistance from Claude Sonnet 4.6 (Anthropic) in diagnosing the root causes, writing the fixes, and verifying them against a real Android 13 extraction.
