Hi, I just started using radiks and my own radiks-server on my Dapp.
I know my radiks-server is working because I can fetch radiks User or Model with fetchList(), even if I get an empty array because nothing is saved yet. If I change the apiServer in radiks configure, the fetchList() method fails. That way, when I put back the correct apiServer url in configure and I get empty array, at least I know my radiks server is up and running.
The problem is when I try to save anything with the save() method.
If I use the example given in the documentation with the simple Todo Model :
class Todo extends Model {
static className = 'Todo';
static schema = {
// all fields are encrypted by default
title: String,
completed: Boolean,
};
}
If I create a new Todo model, and then try to use save(), I get the following error :
> index.js:311
> Uncaught (in promise) TypeError: First argument must be a string, Buffer, ArrayBuffer,
Array, or array-like object.
at fromObject (index.js:311)
at from (index.js:137)

at Object.getPublicKeyFromPrivate (keys.ts:43)
at signECDSA (ec.ts:377)
at Todo.sign (model.ts:211)
at model.ts:131
Same, if y create a user with the method User.currentUser() , and then try to save it, I get the following error :
> fetchUtil.ts:12
> POST https://hub.blockstack.org/store/{adressId}/BlockstackUser/{myBlockstackUserId}
with server error 500
and
utils.ts:401 Uncaught (in promise) Error: Error when uploading to Gaia hub. at Object.<anonymous> (utils.ts:401) at Generator.next (<anonymous>) at fulfilled (tslib.es6.js:71)
Finally, if this time I try to create User with the method User.createWithCurrentUser() method, I get the following error :
> aesCipher.ts:90
> Uncaught (in promise) TypeError: Failed to execute 'encrypt' on 'SubtleCrypto': The provided value is
not of type '(ArrayBuffer or ArrayBufferView)'
at WebCryptoAesCipher.<anonymous> (aesCipher.ts:90)
at Generator.next (<anonymous>)
at fulfilled (tslib.es6.js:71)
With another 500 error after that, saying “Error When Uploading to Gaia Hub”.
And if I try the normal getFile() and putFile() methods without using radiks, that works perfectly, but I really need to use radiks in order for my app to work…
Can you please help me ? I really don’t know what to do
