Unable update custom field : Getting 'anycustomfiield 'to cannot be set. It is not on the appropriate screen, or unknown

Hello Team,
I am unable to create issue with custom field values. Everytime I try tha using frest API get “'anycustomfiield 'to cannot be set. It is not on the appropriate screen, or unknown.”

But able to create the issue manually.

{
“issueUpdates”: [
{
“updates”: {},
“fields”: {
“issuetype”: {
“id”: “10102”
},
“parent”: {
“key”: “SP”
},
“project”: {
“id”: “10215”
},
Profile Testing Required”: “Feature P”
}
}
]
}
I am using bulk issue create API for doing so.
Added this field to required screen but still getting same error. read all the existing solutions but none of them worked.

Response coming:

{
“err”: {
“issues”: [],
“errors”: [
{
“status”: 400,
“elementErrors”: {
“errorMessages”: [],
“errors”: {
“Profile Testing Required”: “Field ‘Profile Testing Required’ cannot be set. It is not on the appropriate screen, or unknown.”
}
},
“failedElementNumber”: 0
}
]
}
}

If a field is not configured to appear on the edit screen, then it will not be in the editmeta, and a field validation error will occur if it is submitted.
