DAG Import Error from lxml import etree MWAA

Question

When DAG executes the followin import`from simple_salesforce import Salesforce` an import error occurs:

```
Broken DAG: [/usr/local/airflow/dags/example_dag_with_taskflow_api.py] Traceback (most recent call last):
  File "/usr/local/airflow/.local/lib/python3.11/site-packages/zeep/transports.py", line 11, in 
    from zeep.utils import get_media_type, get_version
  File "/usr/local/airflow/.local/lib/python3.11/site-packages/zeep/utils.py", line 5, in 
    from lxml import etree
ImportError: libxslt.so.1: cannot open shared object file: No such file or directory
```

The requirements.txt I am using on aws-mwaa-local-runner is the same as what I imported into S3 bucket. The local runner environment does not have the import error. Both are using Airflow version 2.7.2 (latest) and python version 3.11

Answer

Based on the  `ImportError: libxslt.so.1: cannot open shared object file: No such file or directory` error message above, DAG parsing is failing due to the fact it's unable to find the shared object binary "libxslt". Similar issues have occurred when upgrading, and one solution has been to supply the "libxslt-devel" via a startup script to get installed in the environment during update process -

startup.sh script:

```
#!/bin/sh

echo "Updating operating system"
sudo yum install -y libxslt-devel
```

let me know how it goes
