WP - Build error : createSchemaCustomization

[dev-ton]

Hello all,

Im trying to test my first gatsby powered wordpress site (hosted on cpanel), building on Gatsby Cloud, Im using the starter template and I installed WPgatsby and WPgraphql plugins on wordpress. After that I entered the GraphQL endpoint to the gatsby-config. Everything done according tutorials.

When I try to build the site with the default starter GraphQL endpoint, it runs, but as soon as I enter endpoint from my site the build finish at the following step:
`success gatsby-source-wordpress ingest WPGraphQL schema - 0.954s

ERROR

There was an error

not finished createSchemaCustomization - 1.963s`

Does anybody have idea what is a common issue causing this error?

Thank you
