I have sitecore instance on virtual machine, and I am trying to pull and push with my admin credentials only.
But still receiving following error:
Try with update the config Sitecore.Services.GraphQL.Serialization.config
by updating the requireAuthentication
node to false.
<security type="Sitecore.Services.GraphQL.Hosting.Security.GraphQLSecurity, Sitecore.Services.GraphQL">
<requireAuthentication>false</requireAuthentication>
<requireApiKey>false</requireApiKey>
</security>
Hope it helps!
