provide teamsite template trough sitescript: cannot convert Object[] to string

Question

I made a (simple) sitescripttemplate in JSON which I would like to make available for all the users who can create a site.

The inconvenience lies in the fact I only got it working which I write the whole jsoncode in the same PS1 file.

Rather I would prefer to load a file from a directory and work with that content. As you see in my code below

$site_script = Get-Content -Path "./siteTemplate1.json"

$SiteScript = Add-SPOSiteScript  -Title "SiteTemplate1"  -Content $site_script  -Description "SiteTemplate1" 

Add-SPOSiteDesign  -Title "SiteTemplate1"  -WebTemplate "64"  -SiteScripts $SiteScript.Id  -Description "SiteTemplate1"

error I get

Add-SPOSiteScript : Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'Content'. Specified method is not supported.

Thank you Hero to look in to this...

You need to also pass -Raw parameter to the get content for Site Script.

So, modify your code as:

$site_script = Get-Content -Path "./siteTemplate1.json" -Raw

When you use the Raw parameter, it returns the value as one string which can then be passed to the Add-SPOSiteScript command.
