Nested Blockquotes in a table gives the error "This element has conversion issues"


I’m using the new confluence editor and I created a table in an article via the API. When I try to nest block

This is the code I’m trying to put in the table:

<BLOCKQUOTE style="padding-top:0; padding-bottom:0; color:black;"><BLOCKQUOTE style="padding-top:0; padding-bottom:0; color:black;">s3://dk-eisai-sftp/eisai_edw/inbound/weekly/weekly_vector_to_pwc_20211025/stg_sfa_acct_211025.csv.gz</BLOCKQUOTE></BLOCKQUOTE>

This is the result

Any help fixing this is appreciated.
