I deployed a flask app to lambda that includes a function that unzip a small file (124ko), but nothing works as expected. The unzipping clearly fail and I can’t find the reason.

2021-03-23T12:12:46.346+01:00 zipfile corrupt.
2021-03-23T12:12:46.346+01:00 (please check that you have transferred or created the zipfile in the
2021-03-23T12:12:46.346+01:00 appropriate BINARY mode and that you have compiled UnZip properly)
There is no problem when testing locally and the zip file is okay. So I guess the issue comes from lambda.
The code :
with open(file_path, "wb") as binary_file:
binary_file.write(file_content)
Expected behavior : The file should unzip without problem just as it does when the app runs locally or in heroku.
P.S. : I am using postman for testing .
Any suggestion ?
