TROUBLESHOOTING

I can't upload or activate the plugin

  • Is your plugin version compatible with your server version? Check the Compatibility section in the README.
  • Make sure you have configured the SiteURL setting correctly in the Mattermost administration panel.
  • Check the Mattermost logs (yourURL/admin_console/logs) for more detail on why the activation failed.

Error 'Command with a trigger of /gif not found'

This happens when the plugin is not activated, see above section.

Error 'Unable to get GIF URL'

Start by checking the Mattermost logs (yourURL/admin_console/logs) for more detail. Usual causes include:

  • Using GIPHY as provider and using the public beta Giphy. The log will looks like: {"level":"error", ... ,"msg":"Unable to get GIF URL", ... ,"method":"POST","err_where":"Giphy Plugin","http_code":400,"err_details":"Error HTTP status 429: 429 Unknown Error"}. Solution: get your own GIPHY API key as the default one shouldn't be used in production.
  • If your Mattermost server is behind a proxy:
    • If the proxy blocks Giphy, Tenor and Gfycat: there's no solution besides convincing your security department that accessing Giphy is business-critical.
    • If the proxy allows Giphy, Tenor and Gfycat: configure your Mattermost server to use your outbound proxy.

The picture doesn't load

  • Your client (web client, desktop client, etc.) might be behind a proxy that blocks GIPHY, Tenor or Gfycat. Solution: activate the Mattermost image proxy.

There are no buttons on the shuffle message

  • Check your Mattermost version with the compatibility list at the top of this page.

Development

To build the plugin:

make

This will produce a single plugin file (with support for multiple architectures) for upload to your Mattermost server:

dist/com.example.my-plugin.tar.gz

There is a build target to automate deploying and enabling the plugin to your server, but it requires configuration and http to be installed:

export MM_SERVICESETTINGS_SITEURL=http://localhost:8065
export MM_ADMIN_USERNAME=admin
export MM_ADMIN_PASSWORD=password
make deploy

Alternatively, if you are running your mattermost-server out of a sibling directory by the same name, use the deploy target alone to unpack the files into the right directory. You will need to restart your server and manually enable your plugin.
