Error: Invalid wire_type

[marwa...@gmail.com]

Hello,

 

I have an error when I try to encode/decode many messages received from an UDP connexion. This error says me "Error: Invalid wire_type".

 

Could somone explain me what does this error means?

Corrupted data.

If you can print out the binary data using e.g. a debugger, I can take a
look at it.

Thank you for you help.

 

What do you mean exactly by "binary data"?

The input data that you are passing to pb_decode().

Ok.

 

The binary data is:

Hi,

> The binary data is:

Even protoc --decode_raw fails to parse this. At 184th byte, there is a
tag with type "End group", which is deprecated and cannot occur at this
position anyway.

I suggest to compare it with the data that you get from the encode
function at the other end to see if there is some corruption in the
transfer.
