"Flow run failed. Alert: Your operation has been throttled.: Looks like your flow's operation is hitting an action limit designed to protect the connector service being called." (429)

Receiving this error "Flow run failed. Alert: Your operation has been throttled.: Looks like your flow's operation is hitting an action limit designed to protect the connector service being called." (429) in a Power Automate Flow, which is using connection reference to Adobe to convert a word file to PDF.
Throttling does not make any sense as I made sure there is just one API call at a time. This error came out of nowhere, since all worked fine before. Anyone experiencing the same? Thanks in advance!
