I had the error of "Error: Failed to collect page data for api/{route}." Using the nextjs 13 app router. I was using a library called pusher-js and initializing it in one file, pusher.ts, to create a PusherClient instance. It had one parameter, the app key, which was passed in was from process.env (environment variable). This initialized PusherClient was in a page.tsx. I had to hardcode the app key parameter in pusher.ts instead of pulling it from process.env. I don't know why, I think on loading the page.tsx, the PusherClient was not loaded instantly as it had to pull from process.env. edit: I found out why it built locally fine but not on remote server. I was using coolify on my server to build and host the project. For secrets there is an option "Need during buildtime?" which injects the env variables when building the project. For some reason this setting is off by default. I had to turn it on so that secrets got injected into the PusherClient() instance when I was instantiating and importing into that page.tsx file. Turing on the option "Need during buildtime?" on coolify running on my server fixed the issue and I can use |

🤔 Not sure your issue is related. With my issue, the project wouldn’t build, which wouldn’t give the opportunity to deploy it to a server. As a side note, you should not use synchronous calls at all. They will kill your app. Use promises instead, or async/await (which I believe are syntactic sugar on top of promises). |

My project for some reason built locally totally fine, but had build errors on my remote server. I was able to the build error, edited my original answer. |

I don't know if this will help or not, but my issue was that I did not export the getStaticPaths. getStaticPaths and getStaticProps need to be exported for SSG |

I'm encountering problems with my Shopify theme, which I've developed using NextJS. It's preventing me from uploading to the server, and the error seems to be located here. Do any of you have suggestions on what I could do? My current idea is to run "npm build" to build the project. If not, are there alternative solutions? Here the error message from vercel: [22:05:57.157] Running build in Washington, D.C., USA (East) – iad1 |

The problem was my .env was there but the backend server url was not correct, so if you are facing this problem check your backend url or API url your page is making request to. |

You need to update your env variables in settings too. |

All I had to do to fix this is updating my nodejs. |

I encountered this issue only when deploying on Vercel; my local build completed successfully. |

I also encountered this issue locally. Interestingly, Vercel's build didn't fail even though I am using the same node version. Environment variables are also the same. |

Hello,
I’m working on a brand new Next.js project that makes use the app router introduced in Next.js 13. Yesterday, I had everything working but I was only using client components, which prevented me from providing Metadata:
I then started the process of migrating my pages to server components but I had a very hard time doing so. So I though I’d share here what I did, with the hope it would help others.
Symptoms

The issue was I’m using a number of other libraries, such as Material UI, which don’t support server components yet (see mui/material-ui#34896 for this one). They need to add a
'use client'directive on their exports. Until each library you use do it itself, a workaround suggested by @bashonregardless in a comment is to have a file importing and reexporting them, and then only import from this file, not from node_modules. E.g., this is mysrc/lib/react-redux.tsfile:Because, yes, this solution works for other libraries!!
Another option, the one used in mui/material-ui#37315, is to call such libraries only from client components. I didn’t like it much, as it leads to create a helper client component for most (if not all) your server component. You may still like it. In that case, your
page.tsxwould likely look like:Important
next buildgives a page having an issue, but the problem can be in a dependency.layout.tsx.'use client'at the top of my Reduxstore.ts.Beta Was this translation helpful? Give feedback.
