This PR overhauls the static error validation and error messaging across Texera operators to drastically improve the experience for new users during workflow editing. Previously, if a user dragged an operator (like `Projection`, `MySQL`, or `CSV File Scan`) onto the canvas without configuring it yet, the system would immediately throw intimidating and cryptic Java exceptions (e.g., `IllegalArgumentException`, `SQLException: No suitable driver found`, or `/texera (Is a directory)`). Changes proposed: 1. **Frontend Global Catch-all**: Updated the regex logic in `error-frame.component.ts` to cleanly strip internal Java prefixes (like `java.lang.IllegalArgumentException:` or `requirement failed:`) so the user only sees the human-readable part of the error message. 2. **Projection Operator**: Updated `ProjectionOpDesc` to explicitly prompt the user to select an attribute. 3. **Database Sources**: Updated `SQLSourceOpDesc` (and `AsterixDBSourceOpDesc`) to intercept empty database configuration fields and return actionable UI instructions (e.g., "Please enter a valid host name for the database in the properties panel"). 4. **File Scan Sources**: Updated all file scan operators (`ParallelCSV`, `JSONL`, `Arrow`, etc.) to gracefully catch directory selections and missing files before attempting physical reads, replacing IOExceptions with clear prompts to select a valid file from the right-hand panel. ### Any related issues, documentation, discussions? Issue#2735 ### How was this PR tested? Tested manually by rebuilding the `workflow-compiling-service` and dragging every modified operator (Projection, MySQL, PostgreSQL, AsterixDB, CSV, JSONL, Arrow) onto a new workflow canvas. Verified that the Result Panel correctly displays the newly formatted, user-friendly instructions instead of raw Java exceptions. ### Was this PR authored or co-authored using generative AI tooling?
