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.
