# RabbitMQ Message Serialization Errors
---

RabbitMQ Message Serialization Errors refer to a type of incident where there are issues with the serialization of messages being sent via RabbitMQ. This can lead to data corruption and errors within the system. The incident involves debugging and fixing the issue in order to ensure proper functioning of the system.

### Parameters
```shell
export QUEUE_NAME="PLACEHOLDER"

export DELIVERY_TAG="PLACEHOLDER"

export DEAD_LETTER_QUEUE_NAME="PLACEHOLDER"

export RABBITMQ_CONFIG_FILE="PLACEHOLDER"
```

## Debug

### Check if RabbitMQ is running
```shell
sudo systemctl status rabbitmq-server
```

### Check if there are any error logs related to message serialization
```shell
sudo grep -i "message serialization" /var/log/rabbitmq/*
```

### Check if the messages in the queue are corrupted
```shell
sudo rabbitmqctl list_queues name messages | awk '$2 > 0 {print $1}' | xargs -L1 sudo rabbitmqctl eval 'io:format("~s~n", [rabbit_amqqueue:contents("${QUEUE_NAME}")])'
```

### Check the message payload for a specific delivery tag
```shell
sudo rabbitmqctl eval 'io:format("~s~n", [rabbit_amqqueue:lookup("${QUEUE_NAME}", ${DELIVERY_TAG})])'
```

### Check the message payload for a specific message ID
```shell
sudo rabbitmqctl eval 'io:format("~s~n", [rabbit_amqqueue:lookup_by_id("${QUEUE_NAME}", ${<"<message_id}>")])'
```

### Check the message payload in the dead letter queue
```shell
sudo rabbitmqctl eval 'io:format("~s~n", [rabbit_amqqueue:lookup("${DEAD_LETTER_QUEUE_NAME}", ${DELIVERY_TAG})])'
```

## Repair

### Consider implementing message versioning, so that older versions of messages can still be processed correctly even if the serialization format changes. This can help prevent data corruption caused by incompatible message formats.
```shell


#!/bin/bash



# Define variables

RABBITMQ_CONFIG_FILE=${RABBITMQ_CONFIG_FILE}



# Stop RabbitMQ server

sudo service rabbitmq-server stop



# Backup existing config file

sudo cp $RABBITMQ_CONFIG_FILE $RABBITMQ_CONFIG_FILE.bak



# Add message versioning configuration to RabbitMQ config file

sudo echo "rabbitmq_versioning=true" >> $RABBITMQ_CONFIG_FILE



# Start RabbitMQ server

sudo service rabbitmq-server start



echo "Message versioning has been implemented in RabbitMQ."
