PL-900 Practice Question: Refer to the exhibit
Exhibit
Error: The flow 'Send Approval' failed. Action 'Send_an_HTTP_request_to_SharePoint' returned an unsupported status code '403'. The caller does not have permission to perform the action.
Refer to the exhibit. A Power Automate flow fails with the error shown. What is the most likely cause?
⚠ Common exam trap
Many exam-takers assume a flow failure is due to a misconfigured trigger or a malformed URL, but the error message explicitly points to a permission issue, which is a common oversight when reusing connections across environments or after permission changes.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The SharePoint connection used in the flow does not have write permissions
The error message indicates a permission issue when the flow attempts to write to the SharePoint list. Since the flow trigger and HTTP request URL are validated at design time and the SharePoint site is accessible (the flow runs but fails), the most likely cause is that the SharePoint connection used in the flow lacks write permissions on the target list or library.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The flow trigger is misconfigured
Why it's wrong here
Trigger errors would be different.
- ✗
The SharePoint site is offline
Why it's wrong here
403 is a permission issue, not offline.
- ✓
The SharePoint connection used in the flow does not have write permissions
Why this is correct
403 indicates lack of permission.
- ✗
The HTTP request URL is malformed
Why it's wrong here
Malformed URL would give 400, not 403.
