Not able to see previous run details in history tab of allure-report while generating the report via gitlabCI

[dhrupadk]

We are copying the previous run history folder in the allure-results directory and then generating the allure report.
While able to see the history of the previous runs in history tab but not able to browse or see the details of previous runs.
Commands which we are running via our pipeline -
for generating allure results -> - robot --listener allure_robotframework --outputdir results tests/endtoend/endtoend_test.robot
Copying previous run history folder to allure results -> cp -r $PROJECT_NAME/history output/allure/history
generating allure report -> - allure generate output/allure -o allure-report
Can see the history tab having previous runs but not able to see the results of previous tries.
