Logic app Excel online - add a row into a table connector - 400 error 'a value must be provided for item'
I have a logic app that has 3 instances of the excel add a row into a table connector. They add a row into a table in a .xlsx file created earlier in the logic app based on 1 of 3 templates .xlsx files, all with tables set up in them. They are all populated by the same variables (that are set to differing values based on the preceding logic app actions). 2 of the 3 connectors function completely fine, however 1 constantly returns the error in the title -
{
"status": 400,
"message": "A value must be provided for item.\r\nclientRequestId: 2b07c89d-4d9a-4316-aff1-df269785ff52",
"error": {
"message": "A value must be provided for item."
},
"source": "excelonline-we.azconn-we.p.azurewebsites.net"
}
The inputs are all valid values and none of the table items are missing. The set up between the 3 connectors is effectively identical, barring the specific content in the body, which as mentioned does not have any invalid or missing values, so I do not understand why this one connector won't work.
Any advice or suggestion to get around this error would be greatly appreciated. Thanks.
