Hello folks, I have a question/problem.
I'm sending messages from C++ to Java (Play framework) using RabbitMq. So,
in C++ side I used SerializeToString function (also tried SerializeToArray
with char* ). ParseFrom doesn't work in Java using String or byte [].
Detail: in my message, I send base64 images, over 500k characters as String
.
The error is: CodedInputStream encountered an embedded string or message
which claimed to have negative size.
Messages without base64 strings and other attributes, ParseFrom works ok.
Here the complete error:
