and content type [application/octet-stream]

The content type application/octet-stream is a binary format used for transferring unstructured data over the internet. It is used for a variety of purposes, including sending software updates, multimedia files, and other types of data that do not fit into a specific content type.

When a server sends data with the content type application/octet-stream, it is indicating that the data is binary and should not be interpreted as text. This means that the data may contain any combination of characters, including control characters, null bytes, and other non-printable characters.

To process data with the content type application/octet-stream, specialized software may be required to interpret the binary data and extract meaningful information from it. This can include software libraries, APIs, or custom code that is designed to handle specific types of binary data.
