Hey, I can't make a new durable object :

Cannot create binding for class 'Trainer' because it is not currently configured to implement durable objects. Did you forget to apply a --new-class migration to it? [code: 10061]

Cannot create binding for class 'Trainer' because it is not currently configured to implement durable objects. Did you forget to apply a --new-class migration to it? [code: 10061]

But if I try to add it

npx wrangler deploy --new-class Trainer
✘ [ERROR] Unknown arguments: new-class, newClass

npx wrangler deploy --new-class Trainer
✘ [ERROR] Unknown arguments: new-class, newClass

In my wrangler I have

[[durable_objects.bindings]]
name = "DURABLE_TRAINER"
class_name = "Trainer"
[[migrations]]
tag = "v1"
new_classes = ["Trainer"]

[[durable_objects.bindings]]
name = "DURABLE_TRAINER"
class_name = "Trainer"
[[migrations]]
tag = "v1"
new_classes = ["Trainer"]

I already did it once and then I deleted my durable object via dashboard, how to remake one ?

Thanks but I have read all the materials you guys provided. The reason why doing this is to remove errors. I understand that. But what I am saying is that only one read should not consume this number of read because it does not make sense to scan other tables when I just want to get one row. FYI, there is no foreign key in every 8 tables and there are only 6 records in total I will try researching good indices anyway. Thanks for the answer.

Cool 😎 thank you for the info!

Just an addendum here in case anyone sees this in the future that this is for typing only - if the row isn't actually a User no error will be thrown, it will show as a User to Typescript but not actually be a User object 😄

Hi guys, Is the latency between the Worker and the Durable object expected to be around 100-160ms provided that they both are in the same location?

AFAIK, no, but it doesn’t have to, since the storage is synchronous anyway
