EDI X12 file validation error (Azure Logic Apps)

Question

I am trying to validate and parse an X12 file (835/837) in Microsoft Azure using Logic Apps. I have setup my integrations account, tied it to the logic app, schema and agreement is done.

However I get the following error:

{
"errorMessage": "Error: 1 (Miscellaneous error)\r\n\t522: Delimiters are not unique, field and segment separator are the same\r\n\r\n",
"statusCode": "BadRequest"
}

I was told by Microsoft it is an EDI file validation error. Where do I even begin to look to resolve this issue?
