Not getting any output to slack

[worldspawn]

Hi,

i'm trying to integrate this sink. I've am using a webhook pointing to the room i want and have configured the sink

return new LoggerConfiguration()
                    .MinimumLevel.Verbose()
                    .WriteTo.Slack(settings.SlackWebhookUrl)
                    .CreateLogger();

My error is:

I've modified the hook uri shown here.

Are you sure you have a valid webhook url? Check if you're using this packages versions of:

<package id="FSharp.Core" version="4.0.0.1" targetFramework="net451" />
<package id="FSharp.Data" version="2.3.2" targetFramework="net451" />
<package id="Newtonsoft.Json" version="9.0.1" targetFramework="net451" />
<package id="Serilog" version="2.2.1" targetFramework="net451" />

Just released a new version fixing the package dependencies to have the right version.

Hi the webhook url definately works. I dont think i had newtonsoft 9, working with webapi i usually have only 6.0.8 at the most otherwise i start getting mismatches. I ended up using a fork of another slack sink that I then had to fork myself to get working (i'm not savvy with f#).

I'm going to close this as I im not going to spend more time on it. Thanks anyway.

[marcio-azevedo]

Ok, at least try it with the other version dependencies: `

`

@marcio-azevedo doesn't seem to be working on my system. Any insights on how I might be able to troubleshoot?

I've manually verified that the webhook works and my dependencies match yours. Thanks!

[worldspawn]

@yohanmishkin my colleague ended up forking a different implementation. we using it currently - https://github.com/APErebus/serilog-sinks-slack. its not on nuget. we using up to commit f601e0fa74f5526da7945352f5d7d325a8b0028b. Recommend ur fork it

Eg: var webhookUrl = settings.SlackWebhookUrl; if (!string.IsNullOrEmpty(webhookUrl)) { loggerConfig .WriteTo.Logger(lc => lc .MinimumLevel.ControlledBy(loggingLevel) .WriteTo.Slack(webhookUrl)); }

[yohanmishkin]

Thanks @worldspawn! I actually gave this version a shot it seemed to work.

[marcio-azevedo]

@yohanmishkin can you post the error? Also ensure that the dependencies have the proper (NuGet package) version installed, namely: `

`

Closing this issue. Feel free to re-open if you still have an error.
