D1_ERROR: Failed to parse body as JSON

i get randomly on my query

Use ?1 and ?2

Also on a console log check the type of each variable

It has to be string

Perhaps you missed a JSON.parse()

Yo cloudflare people, is there any limitation in just using the D1 that comes with Cloudflare, I mean instead of using posgress or wtv... I've just been using env.db.prepare(query) is it enough for most of SQL queries?

布布鲁诺普雷托 Use ?1 and ?2

VikashOP•7/10/24, 5:18 PM

The same query is working in production, so no issue in code. I just see 3-4 such errors on global error handler out of 200k requests daily

VikashOP•7/10/24, 5:19 PM

The error is D1 type and not in my code

Is this ok to run or the Values should also be with "?" ?

D1 export is not working. X [ERROR] near "index": syntax error at offset 7

I am confused as the d1 worker is functional so it doesn't make sense that there should be an error when exporting

Yeah, we wrote about what we're building here: https://blog.cloudflare.com/building-d1-a-global-database

The Cloudflare Blog

Building D1: a Global Database

D1, Cloudflare’s SQL database, is now generally available. With new support for 10GB databases, data export, and enhanced query debugging, we empower developers to build production-ready applications with D1 to meet all their relational SQL needs

Tarnadas•7/11/24, 7:37 PM

Hey, I've been trying to understand the limitations of D1 when it comes to big integers, but I'm a bit clueless. I have to handle up to 16 byte integers in my application and to my understanding SQLite/D1 only supports 8 byte integer and there is no bigint type. However I've been storing values larger than the max value that can be represented via integer and it didn't throw an error.
How is this possible?

i40west•7/11/24, 8:44 PM

If the value doesn't fit in a 64-bit integer it is converted to a REAL type, which is a 64-bit IEEE floating point value. This can precisely represent integers up to 2^53 and -2^53. Beyond that you will lose precision

i40west•7/11/24, 8:46 PM

You can store big integers as text or blob types, in which case the database won't be able to do calculations with them.

Not currently. They did mention this was a possibility in the future, though

RRahul @kraustifer is there any alternative way to achieve?

森

森@VerseLink (RW)•7/12/24, 6:24 AM

a good workaround might be to have a worker trigger that function when writing to D1 using that worker

Max (@rozenmd)•7/12/24, 7:59 AM

call your API endpoint directly when your business logic calls your function to create a new item?

Max (@rozenmd)•7/12/24, 7:59 AM

though that doesn't help if you're letting folks use the dashboard to directly edit the DB

Why is the location not shown within the dashboard? Would be cool to have an easy way to confirm where the D1 is running, and the data is already available in the api.

Is there a roadmap of when we can get to Sessions API for D1? As in could we expect it to be released soon, or would it take a while?

Cory•7/13/24, 12:14 AM

Are there any plans to add realtime sync to D1?

Isaac McFadyen•7/13/24, 3:59 PM

So I think they're suggesting that you just call your API endpoint when creating a new user.

Isaac McFadyen•7/13/24, 3:59 PM

In your example, rather than creating user in the Function -> firebase calls your endpoint, you just create user and then call your endpoint from the same Function.

Also — and sorry for mentioning you, it would also be really cool if we could add descriptions to the D1’s. So team members can see what the D1 is exactly for.

Same for R2, queue’s and a single Worker.
