Timeout 100 sec error when fetching data from graphqlSource query

[ShakeebAhmed]

Hello,
I am using graphql query to export report, but the issue is when the requested data is too large report.render(false); throw a timeout 100 sec error. I tried increasing the timeout but there is no such option provided by stimulsoft in the latest version too, so i would really like to know the way to solve this issue. This is my code ---

history.DataLoadedAt = DateTime.UtcNow;
await dbContext.SaveChangesAsync();
report.ReportCacheMode = StiReportCacheMode.On;
LogTime(sw, $"[{_report.Name}] Report Render started");
report.Render(false);
LogTime(sw, $"[{_report.Name}] Report Rendered");
history.ReportRenderedAt = DateTime.UtcNow;
await dbContext.SaveChangesAsync();

this is my graphql query --

query zz($search: String!) {
meenadev_suggestedPatientLists(
skip: 0
take: 900000
where: {
and: [
{ treatment: { providerCategories: { any: true } } }
{ name: { contains: $search } }
]
}
) {
items {
id
name
userId

providerCategories {
PayerProgram: name
}

patient {
NationalId: govCode
nationalityNavigation {
countryCode
name
}
partner {
PatientName: name
birthday
}
}
treatment {
id
TreatmentName: name
TreatmentState: state
policy {
code
name
}

meenaRisk {
RiskName: name
}
payerTag {
PayerRisk: name
}

providerCategories {
MeenaProgram: name
}
}
}
}
}
I have also attached the designer --
