homepage : Invalid URL format in composer.json

[michaelphipps]

[Composer\Json\JsonValidationException]
"./composer.json" does not match the expected JSON schema:

• homepage : Invalid URL format

I just updated it to "homepage": "https://github.com/TTRGroup/pipedrive-api-php",

I had the same problem. "homepage" can't be empty. You have to enter some data or remove it.
