Upload multiples files to an entry after its creation (and how to add a caption ?)

@cajazzer thanks for pointing me in the right direction. Yes I see now its in:

@strapi/strapi/lib/services/entity-service/index.js

    if (files && Object.keys(files).length > 0) {
      await this.uploadFiles(uid, entity, files);
      entity = await this.findOne(uid, entity.id, wrappedParams);
    }

Which uses @strapi/strapi/lib/services/utils/upload-file.js

I’ll try creating a patch to fix it and can raise a PR

Were you able to find a solution to this? I tried all the suggestions above but the captions don’t appear to add via the api call.
