Error message

Count should not be greater than 100

What it means

queryPullRequests rejects any requested page size above RestConstants.MAX_PAGE_SIZE (100) for non-administrator subjects with a NotAcceptableException (HTTP 406-style). OneDev caps REST page sizes to protect the server from expensive query executions; only administrators may request larger counts.

Solutions

Set count to 100 or less and paginate using the offset parameter (offset=0,100,200,...).
Run the query as an administrator account/token if large pages are truly required.
Update the integration's page-size constant to RestConstants.MAX_PAGE_SIZE (100).

Example fix

// before
GET /~api/pull-requests?offset=0&count=1000
// after
GET /~api/pull-requests?offset=0&count=100
GET /~api/pull-requests?offset=100&count=100

Defensive patterns

Strategy: validation

Validate before calling

const MAX_PAGE_SIZE = 100
if (!isAdmin && count > MAX_PAGE_SIZE) count = MAX_PAGE_SIZE
// then paginate
for (let offset = 0; ; offset += count) { await query(offset, count) }

Try / catch

try {
  return await api.get(`/pull-requests?offset=${o}&count=${c}`)
} catch (e) {
  if (/Count should not be greater than/.test(e.message)) { c = 100; /* retry */ }
  else throw e
}

Prevention

Cap count at 100 in every OneDev REST integration.
Paginate with offset loops instead of large pages.
Document that only admins may exceed the page cap.
Centralize page-size as a shared constant.

When it happens

Trigger: GET /~api/pull-requests?count=500 by a regular user; hardcoded page sizes over 100 in scripts or integrations; an admin wrote the script (worked), then a normal service account ran it.

Common situations: Pagination loops using count=1000; migration/export tools copying settings between instances; ported scripts from other APIs that allow big pages.
