Paralell API requests provides incorrect date fields

Issue:  Random dates are provided for date fields, when simultaneous or parallel requests are made.

Steps to reproduce:

1. Take a view with more than 25000 records

2. Save the following file as test.sh, providing  appropriate values for VIEW_ID and DOMAIN and ACCESSTOKEN

````

#!/bin/bash

rm $1

ACCESSTOKEN='Removed for security'

for (( i = 1; i < 4; i++ )); do

#statements

echo "https://[DOMAIN].s.xtrf.eu/home-api/browser?viewId=[VIEW_ID]&page=$i&q.task.quote.service=9&maxRows=1000&q.task.invoiceable=yes&q.startDate=from($2)"

curl -X 'GET' \

"https://[DOMAIN].s.xtrf.eu/home-api/browser?viewId=[VIEW_ID]&page=$i&q.task.quote.service=9&maxRows=1000&q.task.invoiceable=yes" \

-H 'accept: application/vnd.xtrf-v1+json;charset=UTF-8' \

-H "X-AUTH-ACCESS-TOKEN: $ACCESSTOKEN">>"$1_$i" &

done

wait

cat $1_*>$1

rm $1_*

````

3. From the terminal run,

./test.sh xtrfRequest1.jsonl 168048709288

4. From the terminal run again,

./test.sh xtrfRequest2.jsonl 168048709288

5. Chech the diff of both files.

Expected Result:

Both xtrfRequest1.jsonl and xtrfRequest2.jsonl are equal and have the same records with the same fields.

Actual result:

Some records(Odds: 4 records in 3000) have their date fields modified to random dates.  For eg, xtrfRequest1.jsonl's 1 record maylook like

    "columns" : [ "268512", "28.02.2023 16:18 GMT", "Service", , "Closed" ]

and the same record  in xtrfRequest2.jsonl  may look like

    "columns" : [ "268512", "27.02.2022 21:15 BST", "Service", , "Closed" ]

Notes:

- Only Date fields are affected

- Only some records are affected and the affected records are random.

- The dates seem to be put from another record, but it maybe completely random as well.
