Cannot find module 'fp-ts/lib/Either'

[ttbarnes]

Hiya, i've bumped the following packages to the latest versions, with node version 21.6.2, NPM version 10.2.4:

"@keystone-6/auth": "^8.0.0",
"@keystone-6/core": "^6.0.0",
"@keystone-6/fields-document": "^9.0.0",

When running npm run dev, which has the following:

"keystone dev --no-ui",

I get the following error, Keystone cannot start:

> keystone dev  --no-ui

Seems to be an issue relating to io-ts.

How can this be resolved please?

[dcousens]

Are you using io-ts or fp-ts in your project?

Thanks for the quick response @dcousens - not specifically, seem to be dependencies within Keystone:

npm ls io-ts
api@1.0.0
└─┬ @keystone-6/fields-document@8.0.2
  ├─┬ io-ts-excess@1.0.1
  │ └── io-ts@2.2.21 deduped
  └── io-ts@2.2.21


npm ls fp-ts
api@1.0.0
├─┬ @keystone-6/core@5.8.0
│ ├─┬ @prisma/internals@4.16.2
│ │ └── fp-ts@2.16.0
│ └─┬ @prisma/migrate@4.16.2
│   └── fp-ts@2.16.0 deduped
└─┬ @keystone-6/fields-document@8.0.2

I am facing similar issue.

@ttbarnes Found any solutions?

Unfortunately not 😢

Further to @ttbarnes, previous release of @keystone-6/fields-document (8.0.2, if I'm not mistaken) complained about missing correct versions of fp-ts:

// yarn add @keystone-6/core@5.8.0 @keystone-6/auth@7.0.3 @keystone-6/fields-document@8.0.2
warning "@keystone-6/fields-document > io-ts@2.2.21" has unmet peer dependency "fp-ts@^2.5.0".
warning "@keystone-6/fields-document > io-ts-excess@1.0.1" has unmet peer dependency "fp-ts@^2.0.0".

Looking forward to a fix.

I think potentially we need to add fp-ts as a peer dependency to the @keystone-6/fields-document package - pull requests accepted!
