Hi there!
I’m a long time cloudflare pages user, never had any problem before but since two days i’m not able to build any pages app that has functions as it logs this right after function compilation

12:03:49.332	Found Functions directory at /functions. Uploading.

I also tried to build the functions locally and they work as intended.
Is there anything i can do to read the logs or get help with this weird behaviour?

Hey,

Do you have a deployment ID?

The Pages deployment ID is a unique build identifier.
It’s the UUID in the browser bar (for example, a URL would be dash.cloudflare.com/ACCOUNT_ID/pages/view/PROJECT/DEPLOYMENT_ID where the deployment ID looks something like a398d794-7322-4c97-96d9-40b5140a8d9b).
This ID can help troubleshoot some issues with Pages builds so if you have a failing build make sure you grab that ID for the Pages team to use.

Yup, here you are 2433982b-267b-4fb6-8197-892a170cc0de

Can you confirm, is there a wrangler.toml file in your project and if so was it always there or was it recently added?

And also if so, is there a pages_build_output_dir or similar param added? Can you provide a copy of this file?

I am also having the same issue - we never had a wrangler.toml file - the guides at the time didn’t have anything about that file for adding functions in front of pages sites.

What is the fix? all my deployments are now failing suddenly

Hey,

Have you got a deployment ID or the pages.dev so we can take a look?

Hey @Walshy I have the exact same error too.

ID: 93317893-1d9b-4d3c-86ce-e7fa2bc7a235

I’m getting the error both with and without a wrangler.toml file.

I should add, on my own site my /functions directory is a symlink. This hasn’t been a problem for the entirety of the site’s life though.

11

A quick update, I have realized that wrangler v2.21.1 does not have this issue, so I’ve just pinned my project to that version for now.

ID cebdd33d-5fd5-4468-96ce-b0db5fd849f7 is one of the failing ones for me

Thank you @graham.hayes @ewpratten I have brought these up to the team

Any update here? I have changes backing up, and need some preview deployments to run for people to review
