Import Json Issue

[diazdennis]

Hello, I'm using your Drawflow very usefully. I added image upload button in one Block. And I export it to JSON and try to import it. But I got error since this upload button has value(fake path). Please update me how to fix this issue asap. Thanks

Thanks for your reply, I already check its issue but my issue is not fakepath. When I try to import JSON which has upload button with file path, I get this error.

Uncaught DOMException: Failed to set the 'value' property on 'HTMLInputElement': This input element accepts a filename, which may only be programmatically set to the empty string.

Kindly check again please.

How do you upload it as a df attribute? or html?

Let me explain. I need to save image path in DB and export flow into JSON and import it again. For example, I added file upload button in one block like this.

I added "df-imagepath" as a attribute in tag. I can save image path in DB using this attribute. When export this flow into JSON and try to import it, I have issue which I mentioned before. When import JSON, current import function try to add value as imagepath to tag. It seems this make issue now.

The problem is that the input type file. It cannot be assigned a value by javascript. Just a blank string.

Therefore a df- attribute would not be the best.

If you need to save the value you could do something like this.

    const nodeId = editor.addNode('test1', 1, 1, 100, 100, 'test1', { imagepath: '', fakeimagepath: '' }, '<div><input type="file" df-fakeimagepath></div>');

    editor.on("nodeDataChanged", (id) => {
        const nodeInfo = editor.getNodeFromId(id);
        const data = nodeInfo.data
        if(data.fakeimagepath !== '') {
           data.imagepath = data.fakeimagepath;
           data.fakeimagepath = ""; 
           editor.updateNodeDataFromId(id, data);
        }
    })
