Getting error while sending messages to a particular group - works for others

[mj2472]

Hello,

While sending messages to one of the group, I consistently keep getting this error. All works well for other numbers and groups - but just not able to send any message to one particular group.

It use to work well till couple days back even for this group. Any pointers? I tried removing axolotl.db but still no luck.

Strangely images are going - but not text.

Group messages are now encrypted (just for text). Described in #1220 and chat-api

[msshapira]

Seems like not all messages are encrypted. Is there any rule to which are and which aren't? On Jan 4, 2016 5:43 PM, "jlguardi" notifications@github.com wrote:

Hi, @tgalal - any timeline on this? or any workaround?

[e0xify]

need a fix for that, too

[tgalal]

WIP in wa16 branch

[RiBro]

@tgalal : Thanks a lot!

Hi, @mj2472. I am new with Yowsup. I barely undertand the layers, but I got send messages and Images to several SIM numbers. could you explain how I use a group in order to send just one Msg and photo. how I can create it?, or use inside a python code with yowsup. I still don't get it. Thanks a lot.

[joaoricardo000]

Algo getting this, did not found any workaround... Not deleting .db nor removing/adding back to group.
Did anyone manage to reverse it?

[relima]

I am also having the exact same problem. Only happens with a particular group (created on Iphone 6+)

[joaoricardo000]

Does anybody knows if that is already fixed on WA16 branch? And does WA16 branch is already functional?

[relima]

@joaoricardo000 i have experimented with wa16 (and with all of its proposed commits) and 1) it still does not fixes this issue and 2) it doesnt look like the wa16 will be a direct replacement to the main and develop branches.

[joaoricardo000]

@relima Thanks! I spent some time debugging the messages exchange on this error, but still not a clue... With me happened on 2 groups that were working for months, with no apparent cause, no new member added/removed, no changes at all...

[relima]

@joaoricardo000 from what I gathered, it is a change on how encryption is implemented on the version of the whatsapp used by the member. It seems Chat API has already fixed this problem. Now, I don`t understand the changes enough as to port them to yowsup. So I will have to wait until someone more knowledgeable can get that sorted out.
