DSBulk unload fails to parse map[value] as provided in query

[msmygit]

Table

CREATE TABLE baselines.map_text_dsbulk (
    k int PRIMARY KEY,
    v frozen<map<text, text>>
);

Add data to the table and validate

token@cqlsh:baselines> create table if not exists map_text_dsbulk(k int primary key, v frozen<map<text,text>>);
token@cqlsh:baselines> insert into map_text_dsbulk (k,v) VALUES ( 1,{'1':'sam'});
token@cqlsh:baselines> insert into map_text_dsbulk (k,v) VALUES ( 2,{'2':'maddy'});
token@cqlsh:baselines> select k, v['2'] as there from map_text_dsbulk;

 k | there
---+-------
 1 |  null
 2 | maddy

(2 rows)

DSBulk version used

% ./dsbulk --version
DataStax Bulk Loader v1.11.0

Output when running via CQLSH:

token@cqlsh:baselines> select k,v['1'] from map_text_dsbulk ;

 k | v['1']

OK, here is a workaround solution to achieving this,

./dsbulk unload -b /path/to/secure-connect-awesome-astra.zip -u token -p "AstraCS:REDACTED" -query "SELECT k,v FROM baselines.map_text_dsbulk" -header false 2> /dev/null | grep '{\\"2\\":.*}' |  awk -F, '{ gsub(/[{}]/, "", $2); split($2, a, ":"); gsub(/"/, "", a[1]); gsub(/"/, "", a[2]); print $1 "," a[2] }' | sed 's/\\//g'

Another flavor is here,

./dsbulk unload -b /path/to/secure-connect-awesome-astra.zip -u token -p "AstraCS:REDACTED" -query "SELECT k,v FROM baselines.map_text_dsbulk" -header false 2> /dev/null | grep "{.*2.*}" |  awk -F, '{ gsub(/[{}]/, "", $2); split($2, a, ":"); gsub(/"/, "", a[1]); gsub(/"/, "", a[2]); print $1 "," a[2] }' | sed 's/\\//g'
