As the error says you are creating too many requests.

A quick search on google brought up that there is a hard limit on the number of requests you're allowed send, found in the usage poilicy of Nominatim:

Requirements

  • No heavy uses (an absolute maximum of 1 request per second).
  • Provide a valid HTTP Referer or User-Agent identifying the application (stock User-Agents as set by http libraries will not do).
  • Clearly display attribution as suitable for your medium.
  • Data is provided under the ODbL license which requires to share alike (although small extractions are likely to be covered by fair usage / fair dealing).

Source: https://wiki.openstreetmap.org/wiki/Nominatim_usage_policy

So in order to fix this error you'll have to make sure that you are not sending more than 1 request per second for your whole application.
