Invalid JSON in options error when omitting the options input entirely

[SimJoSt]

When calling the deployer GitHub action without setting any values for the options input, the following error message appears: Invalid JSON in options
It doesn't break the deployment, however an error message in a successful deployment log feels weird :) And with no actual problems occurring, I was wondering if the error detection is slightly off.
I'm not familiar with the try-catch logic yet, so I cannot provide and improvement as a PR at this time.

Relevant code snippet:

action/index.js

Lines 116 to 126 in 06aeb29

	let options = []
	try {
	let optionsArg = core.getInput('options')
	if (optionsArg !== '') {
	for (let [key, value] in Object.entries(JSON.parse(optionsArg))) {
	options.push('-o', `${key}=${value}`)
	}
	}
	} catch (e) {
	console.error('Invalid JSON in options')
	}

Readme section:

action/README.md

Lines 26 to 29 in 06aeb29

	# Config options for the Deployer. Same as the `-o` flag in the CLI.
	# Optional.
	options:
	keep_releases: 7
