Title: Image Histogram App! ... not working on Heroku

# Image Histogram

Runs fine locally, but having database problems (see below)* on Heroku:

https://image-histogram.herokuapp.com/

See the screenshot uploaded.

I am reusing my previous Node.js application as the backend REST API for computing the image histogram.

https://image-histogram-api.herokuapp.com/

e.g.:

curl -X POST -d '{"imageUrl":"imageUrlGoesHere"}' -H "Content-Type: application/json" image-histogram-api.herokuapp.com/histogram

This does work fine.

*Postgres error message when running on Heroku:

PG::StringDataRightTruncation: ERROR: value too long for type character varying(255) : INSERT INTO "image_histogram_records" ("author", "created_at", "histogram", "image_name", "image_url", "updated_at") VALUES ($1, $2, $3, $4, $5, $6) RETURNING "id"
