    Hi @KRishna,

    Thank you for choosing Photon!

    How large is the data you are trying to send?
    Could you give us a sample/example?

    You can read about Photon Serialization here to find out more about the limits.

    Hi @TeamA,

    Thank you for choosing Photon!

    Photon cannot serialize strings with UTF8 byte size bigger than short.MaxValue (32767).
    Read about "Photon Serialization".
    You can read this FAQ entry: "Is There A Limit For Photon Strings?"
    Also, possibly related since you seem to exchange large messages: "Can I Send A Huge Message Using Photon?".

    It's preferable to download or upload such data using HTTP based web service other than Photon.
