URL: https://github.com/apache/airflow/issues/60924
### Apache Airflow version
3.1.6
### If "Other Airflow 3 version" selected, which one?
_No response_
### What happened?
While deploying Airflow through a Helm chart, I used the following
configuration options:
```
config:
core:
max_templated_field_length: 40960000
```
Upon checking the deployment, I discovered that DAG parsing was failing with
errors.
```
Traceback (most recent call last):
File
"/home/airflow/.local/lib/python3.12/site-packages/airflow/configuration.py",
line 1220, in getint
return int(val)
^^^^^^^^
ValueError: invalid literal for int() with base 10: '4.096e+07'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File
"/home/airflow/.local/lib/python3.12/site-packages/airflow/serialization/helpers.py",
line 64, in serialize_template_field
max_length = conf.getint("core", "max_templated_field_length")
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File
"/home/airflow/.local/lib/python3.12/site-packages/airflow/configuration.py",
line 1222, in getint
raise AirflowConfigException(
airflow.exceptions.AirflowConfigException: Failed to convert value to int.
Please check "max_templated_field_length" key in "core" section. Current value:
"4.096e+07".
```
After investigation, I found that the generated airflow.cfg had the value
stored in scientific notation format. This type conversion from integer to
float occurred during the Helm template rendering process, and the value was
already converted when it was stored in the ConfigMap.
```
[core]
max_templated_field_length = 4.096e+07
```
### What you think should happen instead?
The config parsing should handle large integer type inputs properly.
### How to reproduce
deploy the airflow using Helm chart with the option (large interger type
input in config)
```
config:
core:
max_templated_field_length: 40960000
```
### Operating System
