Summary
Resolving Jama Connect Interchange 504 Gateway Timeout Caused by an Unbounded Excel Formula.
Resolution
A Jama Connect Interchange cloud tenant may throw a 504 Gateway Timeout when an uploaded Excel template contains a formula that references an entire column (e.g., A:A). The formula forces Excel-Functions to iterate over 1,048,576 rows, exhausting memory and triggering the timeout. Limit formulas to the actual data range (e.g., A1:A100) before uploading; this preserves performance and prevents gateway errors.
