Deploy Fails with Illegal Chars In Path ArgumentException

Legacy Uncategorised
1

Hello,

Using Octopus Server 3.3.17, we are getting this error during deployment of a Nuget package step.

System.ArgumentException: Illegal characters in path.

This happens right after a variable substitution step:

Performing variable substitution on ‘C:\Octopus\Applications\QAWeb20\HA.Web.Main\16.06.08.8493_7\Web.config’

I’m not sure if it is happening within the variable substitution step, or whatever comes next.

Is there some way to find out what the path in question is?

Below is the call stack from the error log:

Thanks,

Alan

This deployment step had the “Replace appSettings and connectionString entries in any .config files” setting enabled, which we were not using.

I disabled this setting and this resolved the problem.

If possible I would like to understand what caused this, since this project has been deployed numerous times before without issues.

Hi @avalanchis,

Thanks for reaching out, and glad to hear you found a workaround for your problem.

If you wanna keep troubleshooting this, I’d need to see the content of the Appsettings and connectionstring settings in your .config files. Apparently there was an invalid character in one of them that Octopus wasn’t able to parse.

If you can send the config files, I can check this for you.

Thanks,
Dalmiro
