Ant Design Vue | Upload in Form | How to set initialValue - vuejs2

Question

I'm having problems defining the initialValue in an Upload component, other thing I tried was using a watcher and updating the formValue and the method that update the props FileList. ¿Someone has any idea how this work?
Parent.vue
<Child :file="file"/>
...
async loadFile(item) {
this.loading = true
const { data } = await axios(..., {
...
responseType: 'blob',
})
const file = new File([data], item.name, { type: data.type });
this.file= {
Id: item.id,
Type: item.attributes.type,
IsPublic: item.attributes.is_public,
Descr: item.attributes.descr,
File: [file]
}
this.showForm();
this.loading = false
},
Children.vue
<a-upload
:accept="formats"
:before-upload="beforeUploadEvt"
:disabled="!formats"
:remove="removeFileEvt"
v-decorator="[
'File',
{
valuePropName: 'fileList',
getValueFromEvent: getValueEvt,
rules: [{ required: true, message: 'Select a file' }]
},
]" >
<a-button> <a-icon type="upload" /> Select a file</a-button>
</a-upload>
methods: {
beforeUploadEvt(file) {
this.form.setFieldsValue({
File: [file]
});
return false;
},
removeFileEvt() {
this.formulario.setFieldsValue({
Archivo: []
});
},
getValueEvt(e) {
if (Array.isArray(e)) {
return e;
}
if(e && e.fileList.length > 1) {
return e && [e.fileList[1]];
}
return e && e.fileList;
},
},
watch: {
adjunto: {
immediate: true,
deep: true,
handler(obj) {
if(obj.File) {
this.getValueEvt(obj.File);
// this.formulario.setFieldsValue({
// File: obj.File
// });
}
}
}
}
Trying the most basic example I could think, using the property defaultFileList
<a-upload
:accept="formats"
:before-upload="beforeUploadEvt"
:disabled="!format"
:remove="removeFileEvt"
:default-file-list="this.file.File">
<a-button> <a-icon type="upload" /> Select file</a-button>
</a-upload>
And then, this is the console warnings and errors I got, so seems to be something about type.

If anyone still seeking for an answer for this. You don't need to load file, wrapping your data in appropriate object helps. As in this example
fileList: [{
uid: '-1',
name: 'image.png',
status: 'done',
url: 'https://zos.alipayobjects.com/rmsportal/jkjgkEfvpUPVyRjUImniVslZfWPnJuuZ.png',
}]
<a-upload
....
:file-list="fileList"
