I’m having an issue with gatsby develop and gatsby build when it pulls assets from WordPress. It seems to be related to a missing asset. Usually, the terminal lets you know if there is a 404 getting an error and the URL, but not this time. Do you guys have a clue? Here is a screenshot of the error:

I'm using
“gatsby-source-WordPress-experimental”: “^5.0.2"
WPGatsby 0.8.0
WP GraphQL 1.0.3
@jasonbahl said he could reproduce the error but not have an answer to fix it and post it here to look into it further.
In case anyone needs access to the repository, ping me, and I can add you as a collaborator.
I am facing the same issue and I would like to start working on this. How would you prefer to deal with this issue:
Probably just the specific node, and maybe a notification to know where the error is happening. What do you think?
Also, I'm new at this, but if there is any other way I can help, let me know.
We might need the advice from somebody who maintains this project - this seems to be a big decision
I am having the same issue as well. I was able to use the gatsby-source-worpress@v3 plugin to successfully pull the data. I also tried using gatsby-source-graphql as well and that also worked for me. For now I'm going to use gatsby-source-graphql and eventually switch over to gatsby-source-worpress-experimental when the kinks are worked out. In the experimental docs it looks like migrating from gatsby-source-graphql to gatsby-source-worpress-experimental requires less work than migrating from v3.
with the latest build of gatsby-source-worpress-experimental and WP-Gatsby 0.9 the issue no longer reproducible.
@DanielRiveraHQ & @ryancybul can you please confirm so I can close the issue?
Hi @cstefanache, thanks for the quick response! I'm still running into the same issue after updating gatsby-source-wordpress-experimental and making sure my WP plugins WP Gatsby, WP GraphQL, and WP GraphiQL are all up to date. Below is the console log when I run Gatsby Build. I did not add any additional code to this project other than the gatsby-config.js where I just added the gatsby-source-wordpress-experimental plugin with just the graphql endpoint URL. I don't know if it matters or not but I have about 150 images in my media library and am using the Media Library Categories and reSmush.it Image Optimizer plugins as well. These plugins work with gatsby-source-wordpress@v3.

Exactly the same error here. I have thousands of pictures in my Wordpress site. It looks like it crashes because of a very few of these images. I am trying to have more logs about this problem but it takes a very long time since it starts from the beginning at every gatsby develop run.

Yes, I experience the same issue, it fails when creating MediaItem nodes. This is what I see the moment before the error kicks in:

Right after that I get the exact same error like @ryancybul and @chawax. I was looking into node_modules/gatsby-source-wordpress-experimental/dist/steps/source-nodes/create-nodes/create-remote-media-item-node.js and it seems the error is at line 44: node.link seems to be undefined:
const getMediaItemEditLink = node => {
const {
protocol,
hostname
} = _url.default.parse(node.link); // <- node.link is undefined
const editUrl = `${protocol}//${hostname}/wp-admin/upload.php?item=${node.databaseId}`;
return editUrl;
};
I was able to bypass the issue for test purposes by changing the line to } = _url.default.parse(node.link + "");. I got a bunch of 404 errors for all my images, obviously, but the develop build passes.
Too bad that it's not working, but this is experimental, so I should expect issues down the line.
Same issue here - I've added mine here https://github.com/gatsbyjs/gatsby-source-wordpress-experimental/issues/384
Hi everyone! Is anyone able to provide a reproduction repo and /graphql endpoint I can use to debug this?
Thanks
Hi everyone! Is anyone able to provide a reproduction repo and /graphql endpoint I can use to debug this?
Thanks
I've sent you what I could in PM on slack
I had this problem because there was an image with a broken link in some of my posts. Correcting the URL made the problem disappear.
To find the url that threw 404 error, I wrapped getMediaItemEditLink method in node_modules/gatsby-source-wordpress-experimental/dist/steps/source-nodes/create-nodes/create-remote-media-item-node.js file. Something this way :
const getMediaItemEditLink = node => {
try {
const {
protocol,
hostname
} = _url.default.parse(node.link);
const editUrl = `${protocol}//${hostname}/wp-admin/upload.php?item=${node.databaseId}`;
return editUrl;
} catch (e) {
console.log(node)
}
};
The node.mediaItemUrl property contains the url that caused the problem.
Maybe this piece of code should be wrapped such a way to throw a warning and not an error ?
I'm having a look at this now. I've been out on holidays which is why this one sat so long. I'll keep yall updated!
I've identified the problem (and a few others) and there should be a release out for this tomorrow. Thanks everyone for your patience here!
Great news, thanks !
Great, thank you @TylerBarnes !
A fix has been published in [email protected]! If you're still having problems, feel free to comment here or re-open this issue.
Thanks!
Thanks @TylerBarnes, the issue here is solved. However, the server is not starting for me since 6.1.0. When I downgrade to 6.0.0 and apply my bypass to make it build the server starts again. Something changed that introduced a new issue that I experience: #404
@TylerBarnes It's working on my end. Thank you so much for the fix!
I propose issue for closing
Awesome :D great to hear it's working for yall. Let me know if you run into any other problems!
