[Bug] Can't load file for file token

[Mardoxx]

• Insomnia Version: 5.14.3
• Operating System: win10

Details

1. Create request
2. Add a file token and click it
3. Choose file click Done
4. File token is in warning state

Quick look at error message says:
ENOENT: no such file or directory, open 'C:\Users\Owner\AppData\Local\insomnia\app-5.14.6\UsersOwnerDesktopimage.png'

So looks like it's resolving file path wrongly!

Thanks 😄

Another thing to note is that the live preview takes literally minutes to load and is blocking and eventually hangs and crashes the app for any file over a few KB.

Exporting data shows path of

"value": "{% file 'C:\\\\Users\\\\Owner\\\\Desktop\\\\image.png' %}"

If I change this to

"value": "{% file 'C:/Users/Owner/Desktop/image.png' %}"

it works fine.

This, however, breaks also.

"value": "{% file 'C:\\Users\\Owner\\Desktop\\image.png' %}"

HTH..

Hmm, I hesitate to simply replace all backslashes with forward slashes. I assume this hack would break if a file or folder name contained a forward slash?

It would be nice to figure out the actual cause of this issue. I don't currently have a Windows machine set up for development. Any chance you'd be interested in working on a fix for this?

[Mardoxx]

Sure, I'll give it a go 😄

In case you want/need a place to start... I'd first figure out if the value of path here is what you expect: https://github.com/getinsomnia/insomnia/blob/b3e473071824f0e48e7c26507163182acbe01703/plugins/insomnia-plugin-file/index.js#L18

Thanks, saved me digging 😄

I believe I've replicated the root cause on MacOS as well when having a file with a backslash in it. Happy to try fix this but digging into the code it seems there is some tokenization and untokenization which could be the root cause as I do see some backslash handling/manipulations

	if (!argCompleted && currentArg !== null) {
	if (c === '\\') {
	// Handle backslashes
	i += 1;
	currentArg += argsStr.charAt(i);
	} else {
	currentArg += c;
	}
	}

	for (const arg of tagData.args) {
	if (['string', 'model', 'file', 'enum'].includes(arg.type)) {
	const q = arg.quotedBy || "'";
	const re = new RegExp(`([^\\\\])${q}`, 'g');
	const str = arg.value.toString().replace(re, `$1\\${q}`);
	args.push(`${q}${str}${q}`);
	} else if (arg.type === 'boolean') {
	args.push(arg.value ? 'true' : 'false');
	} else {
	args.push(arg.value);

	return `{% ${tagData.name} ${argsStr} %}`;

Select file with Backslash

Initial loading and preview works

Bring up modal again and preview doesn't work

Request works
The request using the file selected still works so the problem looks to be related to the display/preview

---

This problem seems to be an issue with backslashes in general as a similar problem shows up when trying to Base64encode (similar to above, requests sents do have the correct data, so the problem lies in the just the view portion it seems)

Sorry folks! This was incorrectly tagged as a feature request along with other bugs. I'm going back through and cleaning up, sorry for the inconvenience.
