GraphQL query for markdown excerpt not working within component.

Description

Issue with Markdown excerpts.
The graphql query from within the react component to fetch the prune length seems to be working intermittently. Whereas the query from localhost:8000/___graphql works perfectly fine.

I had seen a similar issue earlier, when the query within the component behaved weirdly due to other problems with the code, for some reason that would also manifest itself on the graphQL query within the component.

This time, I am pretty sure there are no issues in my code. I did a gatsby clean, yet the query from within the component does not seem to be getting refreshed. A query directly from localhost:8000/___graphql works allright.

Any pointers on what could be wrong, as anyone faced similar issues? Do need to clean my node_modules and re-install? I would prefer not doing that.

I tried to add additional fields into the query and those fields are not getting queried. Whereas the same fields get queried successfully from localhost:8000/___graphql.
So I am pretty sure, the graphQL query is failing somewhere within the component. How do we debug this, as there is no error message being displayed?

Ok. This is embarassing. The problem was it was a template component and the query within the file was a leftover, before I turned the component into a template. I updated the query in the gatsby-node.js and it worked ever so smoothly!
