```

these are the data I'm using, only to test if everything is working

[
{
"data": {
"text": "More rapid margin progress."
}}
,
{
"data": {
"text": "Demonstration of gross margin and EBITA margin progression. Better than GDP+ growth."
}}
]

It seems that once the model is trained, the backend isn't able to capture the predicted data, Please if anyone can help I will highly appreciate it
