Keep the larger response within the process output limit.

AzureDevOpsCli.listPullRequests returns full JSON, but VcsProcess truncates output at 1,000,000 bytes. A branch with enough matching PRs and reviewers can now exceed that limit, even when the previous one-result lookup succeeded. The truncated JSON fails decoding, which blocks the PR lookup and creation workflow. (raw.githubusercontent.com)

Limit the returned fields or handle larger responses safely.

@packages/source-control-azure-devops/src/server/AzureDevOpsSourceControlProvider.ts
at line 82:
Adjust the pull-request query configured by the limit in
AzureDevOpsSourceControlProvider so its response stays within VcsProcess’s
output limit, preferably by selecting only fields needed by
AzureDevOpsCli.listPullRequests; if that cannot be guaranteed, handle larger
responses without truncating the JSON. Preserve complete decoding for the PR
lookup and creation workflow.
