The file size for the files in the Salesforce is displaying the correct size/ Numeric values but once moved to the Box displays as “NaNB”.

As per the suggestion from the Box Support, we have upgraded the box version but the issue still persists.

 

Any suggestion would be appreciated.

 

Thank you!

👋 Hi ​@Nabina, thank you for bringing this to our attention.


I’ve checked this internally, and from what we can see so far, the behavior you’re encountering doesn’t appear to stem from the Box for Salesforce integration itself. Since you’re using Mulesoft to write back, it’s possible that the issue is related to that custom implementation rather than the managed package.


I see you already have an open support ticket that has been escalated, and we recommend continuing to monitor that case. Our Support team will review the specifics there and can investigate further once more information is available.


If you’re able to provide additional context on the ticket about how the files are being moved into Box or how the size value is being set, that will also help the team narrow things down more quickly.


Thank you, and we look forward to getting this resolved for you soon.
