Hi,
I am trying to update a metadata field and get an error as seen below.
Will appreciate any help!
Thx
Yoram

Below are 2 REST queries that I am performing.
1. The first on gets all the complianceGroup fields form fieldDefinition for a certain object.
From the query I get the complianceGroup Id and url.
2. The second one tires to patch a new value to the url and id received in the first query.

First select query:
https://um6.salesforce.com/services/data/v49.0/tooling/query/?q=Select+Id,+complianceGroup+From+FieldDefinition+WHERE+EntityDefinitionId+in('Account')

The result is:
Url: /services/data/v49.0/tooling/sobjects/FieldDefinition/Account.Fax
Id: 000000000000000AAA

Second select query:
Header: PATCH https://um6.salesforce.com/services/data/v49.0/tooling/sobjects/FieldDefinition/Account.Fax/000000000000000AAA HTTP/1.1

The result for this query is the following error:
[ {
  "errorCode" : "NOT_FOUND",
  "message" : "The requested resource does not exist"
} ]

This is the java code for the seocnd select query:
private void setComplianceGroupValue(String complianceUrl, String id, ArrayList<String> categories) throws ParseException, IOException, ResponseNotOKException {

        for (Iterator iterator = categories.iterator(); iterator.hasNext();) {
            String currentCagtegory = (String) iterator.next();

            //Set up the HTTP objects needed to make the request.
            HttpClient httpClient = HttpClientBuilder.create().build();
            HttpPatch patch = new HttpPatch(complianceUrl + "/" + id);
            Header oauthHeader = new BasicHeader("Authorization", "OAuth " + loginAccessToken);
            Header prettyPrintHeader = new BasicHeader("X-PrettyPrint", "1");    
            //Header xss = new BasicHeader(("X-XSS-Protection: 1; mode=block"), uri);
            patch.addHeader(oauthHeader);
            patch.addHeader(prettyPrintHeader);
            //patch.addHeader(xss);
            //patch.setHeader("Content-type", "application/json");

            JSONObject jasonCategory = new JSONObject();
            jasonCategory.put("id", id);
            jasonCategory.put("ComplianceGroup", currentCagtegory);
            
            
            StringEntity body = new StringEntity(jasonCategory.toString());
            
            body.setContentType ("application/json");
            //body.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
            patch.setEntity(body);
            // Make the request.
            HttpResponse response = httpClient.execute(patch);
            String getResult = EntityUtils.toString(response.getEntity());
            // if respone is not 200 (ok) than an exception is thrown
            proccessHttpResponse(response, complianceUrl+ "/" + id);
                
            LoggerSingelton.getInstance().getLogger().info("postAttributes result: {}. {}", getResult ,SalesforceRestService.class.getSimpleName());
        }
