Backup script is returning access errors today

[Admin Jira SQS]

I changed the token last friday in the morning, then I executed my Jira backup script, and it worked.

But since tonight it is returning:

{"error":"This feature is only accessible from the UI."}

For instance, when I try to access to 
https://<my site>.atlassian.net/rest/backup/1/export/lastTaskId 
then I get that error message. I have tested it with 2 different sites, and both are returning que message.

Is anyone else having this issue?

My backup script is:

---

#General backup settings

$username = '<my_admin_acount@my_domain.es' # username with domain something@domain
$token = 'my_token' # Token created from product https://id.atlassian.com/manage-profile/security/api-tokens
$destination = 'C:\My_folder\Backup' # Location on server where script is run to dump the backup zip file.
$attachments = 'true' # Tells the script whether or not to pull down the attachments as well
$cloud = 'true' # Tells the script whether to export the backup for Cloud or Server
$today = Get-Date -format yyyyMMdd-hhm
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12;

if(!(Test-Path -path $destination)){
write-host "Folder is not present, creating folder"
mkdir $destination #Make the path and folder is not present
}
else{
write-host "Path is already present"
}

#Convert credentials to base64 for REST API header
function ConvertTo-Base64($string) {
$bytes = [System.Text.Encoding]::UTF8.GetBytes($string);
$encoded = [System.Convert]::ToBase64String($bytes);
return $encoded;
}

$b64 = ConvertTo-Base64($username + ":" + $token);
$auth = $b64;

$string = "cbAttachments:true, exportToCloud:true"
$stringbinary = [system.Text.Encoding]::Default.GetBytes($String) | %{[System.Convert]::ToString($_,2).PadLeft(8,'0') }

$body = @{
cbAttachments=$attachments
exportToCloud=$cloud
}
$bodyjson = $body | ConvertTo-Json

if ($PSVersionTable.PSVersion.Major -lt 4) {
throw "Script requires at least PowerShell version 4. Get it here: https://www.microsoft.com/en-us/download/details.aspx?id=40855"
}

# Create header for authentication
[string]$ContentType = "application/json"

#Create Header
$header = @{
"Authorization" = "Basic "+$auth
"Content-Type"="application/json"
}

# Specific backup settings for every jira/confluence

$account = 'my_site_name' # Atlassian subdomain i.e. whateverproceeds.atlassian.net

# Create header for authentication
[string]$URI = "https://$account.atlassian.net/rest/backup/1/export/runbackup"

# Request backup
try {
$InitiateBackup = Invoke-RestMethod -Method Post -Headers $header -Uri $URI -ContentType $ContentType -Body $bodyjson -Verbose | ConvertTo-Json -Compress | Out-Null
} catch {
$InitiateBackup = $_.Exception.Response.GetResponseStream()
$reader = New-Object System.IO.StreamReader($InitiateBackup)
$reader.BaseStream.Position = 0
$reader.DiscardBufferedData()
$responseBody = $reader.ReadToEnd();
}

$responseBody

$GetBackupID = Invoke-RestMethod -Method Get -Headers $header -Uri https://$account.atlassian.net/rest/backup/1/export/lastTaskId
$LatestBackupID = $GetBackupID

# Wait for backup to finish
do {
$status = Invoke-RestMethod -Method Get -Headers $header -Uri https://$account.atlassian.net/rest/backup/1/export/getProgress?taskId=$LatestBackupID
$statusoutput = $status.result
$separator = ","
$option = [System.StringSplitOptions]::None
$s

if ($status.progress -match "(\d+)") {
$percentage = $Matches[1]
if ([int]$percentage -gt 100) {
$percentage = "100"
}
Write-Progress -Activity 'Creating backup' -Status $status.progress -PercentComplete $percentage
}
Start-Sleep -Seconds 5
} while($status.status -ne 'Success')

# Download
if ([bool]($status.PSObject.Properties.Name -match "failedMessage")) {
throw $status.failedMessage
}

$BackupDetails = $status.result
$BackupURI = "https://$account.atlassian.net/plugins/servlet/$BackupDetails"

Invoke-WebRequest -Method Get -Headers $header -WebSession $session -Uri $BackupURI -OutFile (Join-Path -Path $destination -ChildPath "$account-backup-$today.zip")

And this is its current output:

Hi Admin - Atlassian has deprecated the backup APIs so your script will no longer work.

https://community.atlassian.com/forums/Jira-questions/Backup-Manager-API-deprecation-is-there-going-to-be-a/qaq-p/3120079#:~:text=David%20Malko,alternative%20for%20Standard%20plan%20users: has more details on it.

If you need to continue to do this automatically, you can use a third party app like Rewind (disclosure I'm the CEO). We're working on an API that would allow you to maintain your current functionality - it will be ready this quarter.
