Unable to send Buffer or base64 image via entity service or upload plugin

[cpaczek]

Bug report

Required System information

Node: v18
Strapi: 4.5.6
OS: Windows 10]
DB: SQLite

Describe the bug

There is not a way afaik to send a buffer image or a base 64 image using the Entity Service API or the upload plugin. There is this forum post but it seems like a janky way to do this and I couldn't get it working: https://forum.strapi.io/t/upload-buffer-using-strapi-upload/18807

Steps to reproduce the behavior

Create new strapi app.
Try an upload a buffer using the entity service API.

Expected behavior

Ability to pass buffer or similar node js datatype within entity service

Code snippets

            await strapi.entityService.create('plugin::og-generator.og-image', {
                populate: '*',
                data:{
                    collection: collectionName,
                    collectionID: id
                },
                files:{
                    media: image
                }
            })
        }catch(err){
            console.log(err)
        }```

   uploadFileBinary: async function (file, uuid) {
        const bytesToKbytes = (bytes) => Math.round((bytes / 1000) * 100) / 100;
        const config = strapi.config.get('plugin.upload');

        const createAndAssignTmpWorkingDirectoryToFiles = () => fse.mkdtemp(path.join(os.tmpdir(), 'strapi-upload-'));

        const fileNameNoExt = path.basename(uuid, "jpeg");
        const entity = {
            name: `test ${fileNameNoExt}`,
            hash: `${uuid}_${fileNameNoExt}`,
            ext: "jpeg",
            mime: "image/jpeg",
            size: bytesToKbytes(Number(file.length)),
            provider: config.provider,
            folder: 2,
            tmpWorkingDirectory: await createAndAssignTmpWorkingDirectoryToFiles(),
            // getStream: () => Readable.from(file),
            getStream: () => { return new stream.Readable.from(file)}
        };

        await strapi.plugin('upload').service('upload').uploadImage(entity)

        return strapi
            .query('plugin::upload.file')
            .create({ data: entity });

    },
    ```
    Seems like this is the only way, probably going to make a PR to put this functionality into core.

Hey @cpaczek, after talking with the rest of the content squad, this is actually an enhancement request because we do not support it currently – can appreciate the desire to do so of course! It's also a duplicate of #5297 so i'm going to close this issue in favour of the former, thanks again for contributing to the project :)
