Yes, you face this issue with the last version of prisma because they added the Decimal type. I must convert it to Float to work with Graphql

[omar-dulaimi]

I saw in the past PRS this one https://github.com/paljs/prisma-tools/pull/176 Isn't it supposed to fix this issue?

I'm not sure really about conversion from Decimal to Float, wouldn't that introduce data loss/other issues?

No, it just changes the type name.

176 fix this issue for nexus generator not SDL generator

[AhmedElywa]

For SDL first generator, you need to add Decimal scalar manually in your resolvers

[omar-dulaimi]

Aha okay. Is there anything I can do to speed this ticket resolution?

[omar-dulaimi]

@AhmedElywa Hello again. Could you please elaborate on how to manually do this?

I'm blocked at this issue since yesterday, and I couldn't find mentions of "Decimal" besides in typeDefs and resolversTypes files. We really need to get going with Pal.js

@AhmedElywa Also, how can I change the names of some fields; like "take" I want to change it to "first"

[AhmedElywa]

for adding a custom scalar, look to this example https://www.graphql-tools.com/docs/scalars/#custom-scalar-examples
