Can you show what value your result variable contains.

This happens only when we have huge data in the array.

Seems that your node process runs out of memory during serialization of the "huge array" data. You can try to do the serialization in chunks or increase the memory for the node process.

How can it could be done ?
can you please elaborate a little bit
Any reference code will be helpful

As mentioned in the comments above, the error ususally appears because runnining into a memory issue.

You can try

• to process the serialization of your large array in chunks (e.g. if you have 1000 entries in your array, to a stepwise serialization per 100 entries for instance and concatenate the result).
• increase the memory of your node process aka application (assuming you are using an XSA node module). You can do that via the deployment descriptor or manually (for test reasons) via the SAP HANA XSA Cockpit or the XS CLI (check the scaling options for memory here)
