Description

in azure function for python, we have a data_type parameter that we can set to the value "binary" as per the documentation: https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-input?tabs=python-v2%2Cisolated-process%2Cnodejs-v4&pivots=programming-language-python#decorators

This option is not available for a javascript functions.

The consequence is that when using an extra input of type "blob" the blob is read as a file rather than as a binary and the file's header are modified.
