got the mattermost error "bigbluebutton: Unrecognized remote plugin message" when i recompile this plugin

[GabinhoJean]

Hi,
thank for this great project.

I'm trying to modify some aspects of this plugin.

For testing purposes, I followed the steps below:

1- I cloned this project on my server.

2 - I installed some missing GitHub dependencies using the command "go get"
example: go get github.com/blindsidenetworks/mattermost-plugin-bigbluebutton/server/bigbluebuttonapiwrapper/api

3- I executed the command make build.

after that, everything seems going fine but when I uploaded the builded file bigbluebutton_linux_amd64.tar on my
mattermost server (version 5.21.0 running on ubuntu server 16.04) I got this error:

}

But I tested the lasted release of this project as described in the ReadMe and it's working fine.

Any ideas on this problem, please?

@GabinhoJean can you verify that you configured the plugin correctly before activating it? If that doesn't work, set Mattermost log level to debug and then see what comes up in logs.

What's your build environment like-

• Go version
• Npm version

[ZidaneCA]

Hi @harshilsharma63 , Please I have a similar problem and my npm version is 6.14.4, go version go1.11 linux/amd64

@ZidaneCA do you see any errors in Mattermost logs? try setting log lever to debug and repeating the action. There should definitely be something in logs.

Hi @harshilsharma63 , this is an extract of my logs in debug mode (hope it will be of much help). I notice this line stands out Error relocating /mattermost/plugins/bigbluebutton/server/plugin.exe , (it occurs many times in the logs).

@ZidaneCA are you still facing the issue?

@ZidaneCA are you still facing the issue?

@harshilsharma63 after a long time of trying and failing, I just decided to leave it and go for some version which seemed to work.

[harshilsharma63]

Latest verion of the plugin?

[ZidaneCA]

Haven't tried yet the latest. Will do that and let you know @harshilsharma63
