Not able to post data to custom fields using rest api as server responds with status 400(BadRequest)

[Chunchu Siva Naga Raju]

We have a form where the data from individual fields is stored in corresponding custom fields.

This worked perfectly when we delivered to the client. But It's not working after a month. 

We created new custom fields and shared them to relevant screens. But server responds with bad request when we try to create an issue using custom fields and rest api. 

However, we're able to create the request from service desk portal.

Moreover, We're able to create a request in the project with fields like "Summary" : "something", "Description": "Elaboration". 

So, we see nothing wrong with the api. 

We've checked and double checked to ensure that custom fields are shared to proper screens. 

Yet, we're not able to figure out why the code that ran perfectly a month ago has issues now...

If there're any internal changes we're not aware of, please feel free to let us know.

I tried to be as elaborate as possible. But if you need more information to understand the issue, feel free to shoot a question.

Thanks in advance.

Here's the code snippet:

app.post('/submitproject', isAuthorised, (req,res) => {  

  const reqBody = req.body;  const reqFields = reqBody.requestFieldValues;
