Error while creating app catalog – Updates are currently disallowed on GET requests. To allow updates on a GET, set the ‘AllowUnsafeUpdates’ property on SPWeb

Hello friends,

Recently after creating a dev tenant, I proceeded to create tenant level app catalog site as I was setting up the SPFX environment. I selected ‘Create a new app catalog site’ and added needed details.

New App Catalog Creation

New App Catalog details

I got an error “Updates are currently disallowed on GET requests. To allow updates on a GET, set the ‘AllowUnsafeUpdates’ property on SPWeb” when i tried to create a new catalog site.

New App Catalog Error

After scratching head and after some googling, i found out that we need at least one site collection created other than the default site gets created with tenant. Then only new app catalog creation will work.

New Sample Site Creation

So, i have created a Test site and tried again to create new app catalog and voilà, it worked.

Looking like Microsoft should improve on error handling.

Sharing is caring.
