Issue/Introduction

The Project Canvas fails to save and throws a validation error when a user attempts to reposition or add elements to a column that already contains 100 or more fields. This occurs because the PUT call to the canvasElements endpoint attempts to process all affected elements in a single batch, exceeding the hard-coded API limit of 100 records.

Steps to Reproduce: 

1. Navigate to a Project Canvas and enter Configure mode.
2. Populate a single column with 100 status report fields/elements.
3. Save the current view to establish the baseline.
4. Insert a new column or a new element at the top of the existing list to force a repositioning/re-indexing of the 100 existing fields.

Expected Results: 

The canvas UI should successfully re-index the elements and display the 101st field

Actual Results:

The canvas fails to update and displays the error: "API-1002 : Can only process 100 records at a time"
