Error: Cannot create as TypeComposer the following value: Date.

Description

Can’t launch Dev Server. I just get Error: Cannot create as TypeComposer the following value: Date.

• SchemaComposer.js:313 SchemaComposer.createTempTC [restaurant]/[graphql-compose]/lib/SchemaComposer.js:313:11

• SchemaComposer.js:511 SchemaComposer.addAsComposer [restaurant]/[graphql-compose]/lib/SchemaComposer.js:511:27

Steps to reproduce

gatsby, gatsby new , gatsbystarter, gatsby-plugin-less less, gatsby-plugin-contentful. Should be able to launch dev server

Expected result

should be able to launch dev server. I seem to have conflicting packages. npm WARN @gatsbyjs/relay-compiler@2.0.0-printer-fix.2 requires a peer of graphql@^14.1.0 but none is installed. You must install peer dependencies yourself. npm WARN babel-plugin-remove-graphql-queries@2.6.3 requires a peer of graphql@^14.1.1 but none is installed. You must install peer dependencies yourself. npm WARN ts-pnp@1.0.1 requires a peer of typescript@* but none is installed. You must install peer dependencies yourself.

yet if I download those i then get below npm WARN eslint-plugin-graphql@2.1.1 requires a peer of graphql@^0.12.0 || ^0.13.0 but none is installed. You must install peer dependencies yourself. npm WARN express-graphql@0.6.12 requires a peer of graphql@^0.10.0 || ^0.11.0 || ^0.12.0 || ^0.13.0 but none is installed. You must install peer dependencies yourself. npm WARN graphql-tools@3.1.1 requires a peer of graphql@^0.13.0 but none is installed. You must install peer dependencies yourself. npm WARN ts-pnp@1.0.1 requires a peer of typescript@* but none is installed. You must install peer dependencies yourself.

It’s like certain depend require graphql@14.1.0 and the others require graphql@0.12.0 What should happen? I’m just super frustrated. hopefully, Someone can help me out. I’ve deleted node_modules and package-lock.json. I’ve cleared .cache, npm clear cache, i’ve uninstalled and reinstalled node it’s self. I’m totally at a loss. even others far more experienced than myself can’t seem to help me. Just to clarify totally not upset with anyone I just want this to work. my productivity has went to nothing as I’ve been trying to finish up this project. as it stands I can’t do anything. Thanks all for your help

Actual result

failed. UNHANDLED REJECTION Error: Cannot create as TypeComposer the following value: Date.

What happened. Think it’s just a issue of peer wanting 13 and another wanting 14. but don’t know how to fix

Environment

i had same error here is my fix 1- remove node_modules && package-lock.json 2- yarn install 3- yarn start

[elias-thok]

Same issue, came up today.

Is there any fix for this?

I just ran into that error today and I’m only having 1 version of graphql installed (14.6.0, downgraded from 15.0.0). Removing node_modules & package-lock.json did not fix it.

I’m thinking of putting `rm -rf node_modules && rm -rf package-lock.json" on a keyboard shortcut though, as often as I reach for this. Just press it every morning while drinking coffee, makes node around 90% more robust.

Is this really because of gatsby-plugin-typscript? If yes, why are not more people having this issue?

Edit: Downgrading graphql to 14.6.0 and downgrading gatsby-plugin-typescript to 2.1.27 seems to have solved the issue for today.

PS: Putting this into your .bashrc or .zshrc saves you countless hours from typing it out every time:

alias fuck-off-npm="rm -rf node_modules && rm -rf package-lock.json"
