@bradystroud what happens if you upgrade the CMS to decap 3?

[bradystroud]

We have a Gatsby site, and use the gatsby-plugin-netlify-cms package
Looks like it hasn't been updated to decap yet, see issue
gatsbyjs/gatsby#38553

There is a PR open, so hopefully it gets updated soon 🙂
gatsbyjs/gatsby#38554

If those users clear the cache and log in again, does the error still happen?

[martinjagodic]

@bradystroud how many entries do you have? Is it possible that you are hitting the GitHub rate limit? How does the failed response look in your network tab?

[bradystroud]

Update - we have upgraded from Netlify to Decap CMS but the issue is still there

If those users clear the cache and log in again, does the error still happen?

Yes - the issue persists

how many entries do you have?

@martinjagodic more than 3,200 entries

Is it possible that you are hitting the GitHub rate limit?

Yes - But I would expect an error that says you are hitting the GitHub rate limit if that was the case

How does the failed response look in your network tab?

This error is in the response

Something went wrong while executing your query. This may be the result of a timeout, or it could be a GitHub bug. Please include 058C:63C7C:D2B60A:E85067:6593434F when reporting this issue.
