Note: I'm using Matlab R2019a on a server.

The first time I tried to use the package, I an error when running the following code (<<>> indicates that I had to redact the information):

d = '<<some_path>>\inputdata\';
path1 = genpath(d) ;
path(path1,path) ;

APIKey = '<<my api key>>' ;

b = bls([], APIKey);
data = fetch(b, 'PRS85006092', 'catalog', 'true');

The error I got was the following (note, it traces the error from the original Matlab test script, Untitled2.m):

Dot indexing is not supported for variables of this type.

Error in bls/fetch>blsExtractDataField (line 127)
value = str2double(field.value);

Error in bls/fetch (line 116)
data = arrayfun(@blsExtractDataField, ...

Error in Untitled2 (line 14)
data = fetch(b, 'PRS85006092', 'catalog', 'true');

It seems the error could be traced to the command (around line 116):

        data = arrayfun(@blsExtractDataField, ...
                    response.Results.series(iSeries).data, 'un', 0);

I was able to modify the "fetch" command with the following code replacing the above:

    try
        data = arrayfun(@blsExtractDataField, ...
                    response.Results.series(iSeries).data, 'un', 0);
    catch
        data = cellfun(@blsExtractDataField, ...
                    response.Results.series(iSeries).data, 'un', 0);
    end

This seems to have solved the issue, although I am not sure how.

I used your class file and the function. I created a main and typed
b = bls([], I put my API key here);
data = fetch(b, 'PRS85006092', 'catalog', 'true');

I got this message

File: main.m Line: 1 Column: 15
Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax
error. To construct matrices, use brackets instead of parentheses.

Good day!

I have written a code around your 'fetch.m' function to retrieve data from the BLS API. The code worked fine until recently and now I am getting the following warning message:

"Request failed with message 'The key: provided by the User is invalid. Please provide a proper key for the operation to be successful."

'>key' is just a placeholder in this warning. In my code, I tried two different keys. The first was the BLS key that I always use and which worked until two days ago, and the second is newly created and runs into the exact same problem.
Below is a minimal, reproducible example that should retrieve the CPI data for all items.

blsKey = >key;
b = bls([], blsKey);
fetch(b,'CUUR0000SA0',2019,'catalog','true')

Again, '>key' must be replaced by a character array with a valid key. In my case, it encounters the above warning.
Any help will be greatly appreciated. Many thanks in advance!

Kind regards
