[Bug]: Fix "[JwkDocumentExtensionError]: storage operation failed: key storage error" when using serde_wasm_bindgen::to_value()

[chrisgitiota]

Bug description

The current implementation of the impl_wasm_json macro and the TryFrom<&Object> for MapStringAny implementation use the deprecated JsValue::from_serde() function (just search for #[allow(deprecated)] in the repository to find it).

Replacing JsValue::from_serde() with serde_wasm_bindgen::to_value() is currently not possible because this leads to an [JwkDocumentExtensionError]: storage operation failed: key storage error in the identity_wasm examples, which is caused by the usage of serde_wasm_bindgen::to_value() in the impl_wasm_json macro.

Printing the return values of the impl_wasm_json macro (using the instrumented macro code listed at the bottom of this ticket) while executing example 0_create_did leads to the following console logs:

With JsValue::from_serde():

With serde_wasm_bindgen::to_value():

--------------------------JsValue(Object({"key_id":"z1KXwMdCrBUuk1CYzBo-tyOOa5o","jwk":{}}))

We need to find out why the jwk field serealization/de-serialization fails and after having fixed that, replace all JsValue::from_serde() usages with serde_wasm_bindgen::to_value().

This is the instrumented impl_wasm_json macro code:

macro_rules! impl_wasm_json {
  ($wasm_class:ident, $js_class:ident) => {
    #[wasm_bindgen(js_class = $js_class)]
    impl $wasm_class {
      /// Serializes this to a JSON object.
      #[wasm_bindgen(js_name = toJSON)]
      pub fn to_json(&self) -> $crate::bindings::wasm_error::Result<wasm_bindgen::JsValue> {
        use $crate::bindings::wasm_error::WasmResult;
        //let ret_val = serde_wasm_bindgen::to_value(&self.0).wasm_result();
        let ret_val = wasm_bindgen::JsValue::from_serde(&self.0).wasm_result();
        if let Ok(val) = &ret_val {
          $crate::console_log!("--------------------------{:?}", val);
        }
        ret_val
      }

      /// Deserializes an instance from a JSON object.
      #[wasm_bindgen(js_name = fromJSON)]
      pub fn from_json(json: &wasm_bindgen::JsValue) -> $crate::bindings::wasm_error::Result<$wasm_class> {
        use $crate::bindings::wasm_error::WasmResult;
        json.into_serde().map(Self).wasm_result()
      }
    }
  };
}
