Failed to export Matrix Item# {ParentItemId} (Id: {ParentInternalID}) | Invalid Format for Matrix option. Use \"--\"

When previewing the data in the Celigo NetSuite Export for the Matrix Item Flow I get the following error message:

{
"page_of_records": [
{
"record": {
"code": "shopify_matrix_item_export_error",
"message": "Failed to export Matrix Item# {ParentItemId} (Id: {ParentInternalID}) | Invalid Format for Matrix option. Use \"--\"",
"source": "pre_send_hook_ss",
"resolved": false,
"occurredAt":
}
}
]
}

I was using following matrix formatting format {itemid}-{custitem_}
I am tried to follow the error message and change the matrix naming convention in Netsuite under Items >> Accounting tab to the following {itemid}--{custitem_} (notice that I changed from '-' to '--':

Still the error is persistent. Anyone in the community experienced the same error before?

Hi Sujit,

You need to use it int he below format ->
{itemid}-{custitemxx}

Also I have seen this issue when we don't the set the shopify variation theme.

Can you try the above internally and confirm if that helps.
