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

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
Lauritz
