I suspect this problem might occur due to one of two issues.

The first possibility is an issue during the download of the JSON file. It happens occasionally and seems to be associated with a server-side limit. If this is the case, the best solution is to try again after a while.

The second possibility is a problem when saving the JSON file locally, if the argument cache_json is set to TRUE (the default). A potential solution is to explicitly set this argument to FALSE and try again.

If all the user wants is bank-level data from 2017 or more recently, brazilianbanks provides out-of-the-box a dataset that might be helpful. This dataset (currently only until Dec 2021 but in the near future also including the most recent data) is accessible with the following code:
