--- TASK BEGIN ---
You'll find a log file called `application.log` in the `./input` directory. Parse this log file and extract the following information:

1. Count the total number of ERROR and WARNING level messages
2. Extract all unique IP addresses that appear in the logs
3. Find all timestamps where errors occurred
4. Identify the most common error message (if any patterns exist)

Generate a JSON file called `log_analysis.json` with the following structure:

```json
{
  "total_errors": <number>,
  "total_warnings": <number>,
  "unique_ips": ["ip1", "ip2", ...],
  "error_timestamps": ["timestamp1", "timestamp2", ...],
  "most_common_error": "<error message or null>"
}
```

Make sure to handle different log formats gracefully and extract the relevant information accurately.

PS: You are currently working in an automated system and cannot ask any question or have back and forth with an user.

I need to analyze the `application.log` file in the current directory and generate a `log_analysis.json` file.

Since the structure of the log file is unknown, I will read a sample of the file first to understand its format. Then, I will use a combination of bash tools (`grep`, `awk`, `sed`, `sort`, `uniq`) to parse the log and extract the required information.

First, let me confirm the file exists and read its first few lines.

The log file format appears to be `[TIMESTAMP] [LOG_LEVEL] [IP_ADDRESS] [MESSAGE]`.

I will now execute a single `bash` command to extract all the required data and format it into a JSON string, which I will then write to `log_analysis.json`.

**Extraction Strategy (using a single Bash command):**

1.  **Count Errors/Warnings:** Use `grep -c` for each.
2.  **Unique IPs:** Use `grep -oE` to extract IPs (regex `[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}`), pipe to `sort -u`.
3.  **Error Timestamps:** Use `grep ERROR` and extract the first two columns (date and time).
4.  **Most Common Error:** Use `grep ERROR`, strip the IP/timestamp/level to get only the message, pipe to `sort | uniq -c | sort -nr` to find the most frequent one.

**Bash Command Construction:**

Since the log is delimited by simple spaces, I'll use `awk` to process the fields. Specifically, the timestamp is in fields 1 and 2, the level in field 3, IP in field 4 (inside brackets), and the message starts at field 5.

I will use `awk` for counting and extracting and then format the final output.

Final plan:
1.  Run a single Bash script to perform all analysis and print the raw results.
2.  Format the raw results into the final JSON structure and write it to `log_analysis.json`.

```bash
# 1. Total Counts
TOTAL_ERRORS=$(grep -c ' ERROR ' /app/input/application.log)
TOTAL_WARNINGS=$(grep -c ' WARNING ' /app/input/application.log)

# 2. Unique IPs (Assuming IP is always immediately after the log level, inside brackets)
UNIQUE_IPS=$(grep -oE '\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\]' /app/input/application.log | sed 's/\[//;s/\]//' | sort | uniq | awk '{printf "%s\"%s\"", sep, $0; sep=",";}' )

# 3. Error Timestamps (Fields 1 and 2 of lines containing ERROR)
ERROR_TIMESTAMPS=$(grep ' ERROR ' /app/input/application.log | awk '{printf "%s\"%s %s\"", sep, $1, $2; sep=",";}' )

# 4. Most Common Error Message (start from field 5, find max count)
MOST_COMMON_ERROR_LINE=$(grep ' ERROR ' /app/input/application.log | awk '{$1=$2=$3=$4=""; sub(/^ +/, ""); print}' | sort | uniq -c | sort -nr | head -1)

# Check if any errors were found
if [ -z "$MOST_COMMON_ERROR_LINE" ]; then
    MOST_COMMON_ERROR_COUNT=0
    MOST_COMMON_ERROR="null"
else
    MOST_COMMON_ERROR_COUNT=$(echo "$MOST_COMMON_ERROR_LINE" | awk '{print $1}')
    MOST_COMMON_ERROR_RAW=$(echo "$MOST_COMMON_ERROR_LINE" | awk '{$1=""; sub(/^ +/, ""); print}')
    MOST_COMMON_ERROR="\"$MOST_COMMON_ERROR_RAW\""
fi

# Print all results in a format easy to parse (or directly as JSON)
echo "{"
echo "  \"total_errors\": $TOTAL_ERRORS,"
echo "  \"total_warnings\": $TOTAL_WARNINGS,"
echo "  \"unique_ips\": [$UNIQUE_IPS],"
echo "  \"error_timestamps\": [$ERROR_TIMESTAMPS],"
echo "  \"most_common_error\": $MOST_COMMON_ERROR"
echo "}"
```

I will execute the script to get the JSON output. Note that I am carefully managing quotes and commas in the result variable constructions to produce valid JSON.
