In ejabberd 18.01-2, installed in lxc container Ubuntu 18.04 Bionic LTS using apt, I'm trying to setup mod_http_upload.
Following the documentation, in the section listen, I have
listen:
...
-
port: 5443
module: ejabberd_http
tls: true
request_handlers:
upload: mod_http_upload
However, when I restart the service, I can see in the log /var/log/ejabberd/error.log:
2019-11-11 13:47:06.923 [error] <0.379.0>@ejabberd_listener:validate_module_option:604 ignoring listen option 'request_handlers' with invalid value: [{upload,mod_http_upload}]
You are reading configuration examples from the online documentation, which documents the latest released ejabberd version, 19.09.
And you are using those examples with your old ejabberd 18.01. It isn't a surprise if something goes wrong.
In this case, the problem is in the syntax, it's easy to fix, and you can notice it if you look at the ejabberd.yml that comes as example in your ejabberd 18.01 installation:
The last line in that example configuration can be:
new syntax upload: mod_http_upload if you use the new ejabberd 19.09
old syntax "/upload": mod_http_upload if you use the new ejabberd 19.09
but you can only use the old syntax "/upload": mod_http_upload if you use the old ejabberd 18.01
