The extension stops receiving messages from native app after receiving a message

[DevHexa]

Hi,

On windows, with chrome 64 bits and native application 32 bits.
My extension stops receiving messages after receiving the following message.
I don't think it's a message length issue, as much longer messages are fine. I also don't see any blocking characters (I base64 encoded the message content to avoid this kind of problem...).
But,  if i delete the last character in the item "data" , the message is fine !!!!

        If i replace the last character by another, the message is not fine !!!
An idea ?
Thank you

The message : {"close":false,"data":"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","requestId":11}

Hi,

On first thought, this sounds like a possible issue with how the message is being encoded or read.

Do you see the same problem sending the same message with the sample code here?

Hello, 

I found the problem: my native application calls a DLL that modifies the standard output.

I need to set the binary format for each message.

Thank you.

Thanks for following up! It is always nice to hear an update :)
