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.

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.

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.

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.
