If you’ve applied the fix but still see errors:

public function setFileNameAttribute($value) $this->attributes['file.name'] = $value; from flask import request raw_data = request

app.use((req, res, next) => if (req.body && typeof req.body === 'object') Object.keys(req.body).forEach(key => if (key.includes('.')) const newKey = key.replace(/\./g, '_'); req.body[newKey] = req.body[key]; delete req.body[key]; ); next(); ); Django Model Fix:

var options = new JsonSerializerOptions DictionaryKeyPolicy = JsonNamingPolicy.CamelCase, // Custom converter to handle dots ; Model Fix: '_'): v for k

const schema = new mongoose.Schema( // Use a custom getter/setter "file.name": type: String, alias: 'fileName' ); // Or use `toJSON` transform schema.set('toJSON', transform: (doc, ret) => if (ret['file.name']) ret.fileName = ret['file.name']; delete ret['file.name']; return ret; );
