# Pull Requests - Azure DevOps rejects a PR with a long description

**Symptoms**

* Creating a pull request in Azure DevOps fails, especially for **bulk** fixes where many issues are combined into a single PR.
* The failure is on the Azure DevOps side (the PR is rejected rather than created).

**Likely cause**

Azure DevOps enforces a **maximum length of 4000 characters** on a pull request description. A bulk PR that aggregates many fixes can produce a description that exceeds this limit, and Azure DevOps rejects it.

**Resolution**

1. Create **smaller pull requests** — fewer fixes per PR, or individual PRs per issue — so each PR description stays within Azure DevOps's 4000-character limit.
2. Retry PR creation.
