**I have the same issue with version 3.2**
Here is my environment setup in dolphinscheduler_env.sh
```bash
export SPARK_HOME=${SPARK_HOME:-/data/spark3}
export PYTHON_LAUNCHER=${PYTHON_LAUNCHER:-/usr/local/python3/bin/python3}
export DATAX_LAUNCHER=${DATAX_LAUNCHER:-/usr/local/datax/bin/datax.py}
export
PATH=$HADOOP_HOME/bin:$SPARK_HOME/bin:$PYTHON_LAUNCHER:$JAVA_HOME/bin:$HIVE_HOME/bin:$FLINK_HOME/bin:$DATAX_LAUNCHER:$PATH
```
When I pass the task or the result of these variables
```bash
echo " ------shell task 1 ------"
echo "The python launcher program is ${PYTHON_LAUNCHER} "
echo "The spark home is ${SPARK_HOME}"
echo "The datax launcher program is ${DATAX_LAUNCHER}"`
```
As shown in the log below, they are all null.
```text
------shell task 1 ------
The python launcher program is
The spark home is
The datax launcher program is
```
