Issue/Introduction

We are getting below error when upload file is done through Gateway :

"message": "Required MultipartFile parameter 'file' is not present"

 

1) Working scenario - Target endpoint invoked directly from postman with below headers,

 

Content-Type - multipart/form-data

Accept - application/json

file - ABC.zip(Contains .csv and metadata.properties.xml)

 

2) Not Working through Gateway - Target endpoint invoked  from postman through Gateway with below headers,

 

Content-Type - multipart/form-data

Accept - application/json

file - ABC.zip(Contains .csv and metadata.properties.xml)

 

The possible errors we are seeing,

 

"message": "Required MultipartFile parameter 'file' is not present"

"message": "This batch does not have any content files"

(in this case filename while reaching target the file name name is  received as timestamp.zip where target is not considering the files as per the logs in target server)

 

 

 

 

 

 

 

 

 

 

 

 

 

Environment
