After successfully generating a signature, you tried to post a document into a portal with the signature. However, you encountered an exception

"error": {
"propertyName": null,
"propertyPath": null,
"errorCode": "Err03",
"error": "Invalid Signature",
"innerError": [
{
"propertyName": "value",
"propertyPath": "documents.signatures.value",
"errorCode": "4043",
"error": "4043:message-digest attribute value does not match calculated value[message-digest attribute value does not match calculated value]",
"innerError": []
}
Please help me how resolve this error.
