Error when running in standalone mode

[khawerrind]

Getting the following error when running the connector in standalone mode locally:

2023-12-13 12:02:08 Caused by: org.apache.kafka.connect.runtime.rest.errors.BadRequestException: Connector config {java_base_dir=$( cd -P "$base_dir/../share/java" && pwd ), fi=, shift=, for=library in "kafka" "confluent-common" "kafka-serde-tools" "monitoring-interceptors"; do, echo="USAGE: $0 [-daemon] connect-standalone.properties", dir="$java_base_dir/$library", -daemon)=, else=# Fallback to normal default, LOG4J_CONFIG_ZIP_INSTALL="$base_dir/../etc/kafka/connect-log4j.properties", COMMAND=$1, if=[ "x$KAFKA_HEAP_OPTS" = "x" ]; then, export=CLASSPATH, case=$COMMAND in, ;;=, LOG4J_CONFIG_NORMAL_INSTALL="/etc/kafka/connect-log4j.properties", KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:$base_dir/../config/connect-log4j.properties", then=, elif=[ -e "${LOG4J_CONFIG_ZIP_INSTALL}" ]; then # Simple zip file layout, CLASSPATH="$classpath_prefix$dir/*", done=, exit=1, base_dir=$(dirname $0), classpath_prefix="", EXTRA_ARGS="-daemon "$EXTRA_ARGS, exec=$(dirname $0)/kafka-run-class $EXTRA_ARGS org.apache.kafka.connect.cli.ConnectStandalone "$@", *)=, esac=} contains no connector type

Do you have any idea how to resolve this?

Hi @khawerrind!

The error message you shared indicates that the connector.class property is missing in the properties file. If you are following the example provided in the README.md file, it suggests that you haven't created the docker-compose-connector.properties file as specified in the configuration section.

To resolve this issue, please follow these steps:

1. Create a docker-compose-connector.properties file in the /config directory.
2. You can use the example file provided as a template.
3. Ensure that you copy the example file content into the new docker-compose-connector.properties file.
4. Don't forget to provide your Ably key in the appropriate field within the docker-compose-connector.properties file.

By completing these steps, you should address the error, and your configuration should work as intended.
