gatsby: GraphQL Error Unknown field that happens randomly

Description

When I run gatsby develop or build it fails sometimes on the first few runs and then without any code changes running the same command after will build successfully.

For example, today I started the project and had to repeat: gatsby clean && gatsby develop, several times until it starts working. I’m fetching data from a remote GraphQL and not the local or md files, etc. Checked the remote GraphQl and is always fully working (tested with HTTP Post requests sending the query + variables, returns data absolutely fine); then checked the local __graphpql and could not find the remote GraphQL.

Steps to reproduce

It’s random! Here’s a youtube video where I demonstrate the issue ( https://youtu.be/2uniflq5I-Q )

Expected result

I expect to not have to run the command several times to make it work

Actual result

`GraphQL Error Encountered 2 error(s):

Unknown field ‘wpcms’ on type ‘Query’. Source: document`
