Persistent Whitespace Changes in confluent_schema resources

[S1M0NM]

Terraform Provider Version: 1.83.0 and 2.1.0
Terraform Version: 1.8.5 (also tested 1.9.5)

Since upgrading the Terraform provider to version 2.1.0, I've been encountering a recurring issue with whitespace changes in the same 4 confluent_schema resources.
Despite applying the plan changes, the same whitespace changes reappear in subsequent plans.

Expected Behavior: Once the plan changes are applied, subsequent plans should not show any changes if no modifications were made to the configuration.

Actual Behavior: Whitespace changes for the confluent_schema resources reappear in every plan, even after they have been applied.

Additional Information:

• The issue does not seem to be affected by different line endings (LF or CRLF).
• This behavior started occurring after upgrading from version 1.55.0 to 1.83.0 and still persists with 2.1.0

Plan output

# module.<module-name>.confluent_schema.schema["<index>"] will be updated in-place
  ~ resource "confluent_schema" "schema" {
        id                          = "lsrc-<id>/<subject>/latest"
      ~ schema                      = jsonencode( # whitespace changes
            <schema_content>
        )
        # (8 unchanged attributes hidden)

        # (2 unchanged blocks hidden)
    }

Terraform Config:

resource "confluent_schema" "schema" {
  for_each = { for schema in var.schemas : schema["subject"] => schema }

  subject_name = each.value["subject"]
  format       = each.value["format"]
  schema       = file(each.value["schema_file_path"])

  credentials {
    key    = var.schema_registry_api_key.id
    secret = var.schema_registry_api_key.secret
  }
  rest_endpoint = var.schema_registry.rest_endpoint

  schema_registry_cluster {
    id = var.schema_registry.id
  }
