Task name

HelmInstaller@1

Task version

1.272.0

Issue Description

HelmInstaller@1 task started failing today with RangeError: Maximum call stack size exceeded error message.
Task is consistently failing when it tries to cahce version of Helm which was not not already cached on the build agent.
Using helmVersionToInstall parameter makes no difference - if version was not cached previously the task fails.
Complete debug log is over 3Mb, I'll paste redacted version with repeating parts removed.

Another observation (may be irrelevant though).
This only happens on build servers which joined EntraID and use EntraID user to run the agent (like azureagent@company.com and the agent is installed in path /home/azureagent@company.com/agent/.
On the agents not joined EntraID where task works the path is a bit shorter: /home/azure/agent/

This seems to be the reason: microsoft/azure-pipelines-task-lib#1166
