Error parsing file sent by FormData to Jets

Hi everyone, I’m developing an API endpoint that receives forms params and a file in the same request and save it using Carrierwave. When I test it through a HTML form or through an Insomnia request, I get the following error:

JSON::GeneratorError at /[path]

source sequence is illegal/malformed utf-8

Ruby /home/uanderson/.rbenv/versions/2.7.7/lib/ruby/gems/2.7.0/gems/activesupport-6.1.4.7/lib/active_support/core_ext/object/json.rb: in to_json, line 40
Web POST 127.0.0.1/[path]

Looking at the stack trace, it appears that the error originates from an attempt to log the request:

/home/uanderson/.rbenv/versions/2.7.7/lib/ruby/gems/2.7.0/gems/jets-3.1.1/lib/jets/controller/base.rb: in json_dump

  display_event["queryStringParameters"] = parameter_filter.filter(display_event['queryStringParameters'])
  display_event["pathParameters"] = parameter_filter.filter(display_event['pathParameters'])
  json_dump(display_event)
end

# Handles binary data safely
def json_dump(data)
  JSON.dump(data) ### <= HERE
rescue Encoding::UndefinedConversionError
  data['body'] = '[BINARY]'
  JSON.dump(data)
end

def controller_paths
  paths = []

/home/uanderson/.rbenv/versions/2.7.7/lib/ruby/gems/2.7.0/gems/jets-3.1.1/lib/jets/controller/base.rb: inevent_log

    display_event['body'] = '[BASE64_ENCODED]'
  else
    display_event['body'] = parameter_filter.filter_json(display_event['body'])
  end

  display_event["queryStringParameters"] = parameter_filter.filter(display_event['queryStringParameters'])
  display_event["pathParameters"] = parameter_filter.filter(display_event['pathParameters'])
  json_dump(display_event) ### <= HERE
end

# Handles binary data safely
def json_dump(data)
  JSON.dump(data)
rescue Encoding::UndefinedConversionError
  data['body'] = '[BINARY]'

/home/uanderson/.rbenv/versions/2.7.7/lib/ruby/gems/2.7.0/gems/jets-3.1.1/lib/jets/controller/base.rb: in log_start

    # Documented interface method, careful not to rename
    def log_start
      # JSON.dump makes logging look pretty in CloudWatch logs because it keeps it on 1 line
      ip = request.ip
      Jets.logger.info "Started #{@event['httpMethod']} \"#{@event['path']}\" for #{ip} at #{Time.now}"
      Jets.logger.info processing_log
      Jets.logger.info "  Event: #{event_log}" ### <= HERE

The curl request:

curl --request POST \
  --url http://127.0.0.1:8888/[path] \
  --header 'Authorization: Bearer ey...' \
  --header 'Content-Type: multipart/form-data' \
  --form 'status[user]=email@email.com' \
  --form 'status[date]=2023-09-26' \
  --form 'status[value]=600' \
  --form 'status[file]=@C:\Users\Uanderson\Pictures\file1.png' \
  --form 'status[uuid]=1'

Has anyone encountered this error before?

Do you have an example repo? If so can you send it with steps to replicate?

Have you tried different photos? Might be as simple as the photo is corrupt.

Is the request making it to your controller or is jets breaking before it gets to your app?
