When publishing a workbook created in Tableau Desktop to Tableau Server or Tableau Cloud, you may encounter the following error message, and the publishing process will stop.

> Unexpected Error  
> An error occurred while publishing the workbook.  
> Error Code: 0505B44A  
> HTTP bad request

This error primarily occurs when the **'Project Name' on the Tableau Server contains a slash (`/`)**.

In a web environment, a slash (`/`) is used to separate the hierarchy of a URL path. Therefore, if a project name includes a slash, the server misinterprets it as a non-existent subfolder path rather than a single project name. This confusion results in a communication error, specifically an 'HTTP bad request'.

### Solution

To resolve this error, log in to your Tableau Server and remove the slash (`/`) from the project name. If you need to separate words, it is recommended to use a hyphen (`-`) or an underscore (`_`) instead. Once you have corrected the project name, try publishing again from Tableau Desktop, and the workbook will upload successfully.
