Hi Experts,

Please help me resolving this issue

Hi Gowtham,

As mentioned by Krishna, as a rule of thumb you should always fill the exporting parameter er_entity in case of any Create or Update method.

Framework always expects the created/updated value which shoud be rendered back to UI. Attachments/media is an excpetion here where we export other file attributes Like created by, creation date etc.

thanks for your blog. i have missed the er_entity. now in backend table its get updated but in gateway client i getting the error as 500 internal server error as 'Invalid or no mapping to system data types found'

for this error you need to redefine the DEFINE method in <.....>MPC_EXT class and set the mime type property accordingly. Basically system is trying to tell you that the media entity/stream file does not have an associated mime type like pdf,xlsx,doc,etc.
