I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs
...ANSWER
Answered 2022-Mar-16 at 07:01First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".
January 11, 2022 Final brownout.
This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.
Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.
As noted by Jörg W Mittag:
For GitHub Actions:There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".
Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.
The permanent shutdown is not until March 15th.
As in actions/checkout issue 14, you can add as a first step:

QUESTION
I'm trying to create a chart with echarts.apache which resembles the chart below...also if any other charting library makes this easier then please shout!
The chart needs to have Coloured areas which highlight the data, for ex :
xAxis (start: 0, end: 4) and yAxis (start: 0, end: 6) => Green background
xAxis (start: 0, end: 4) and yAxis (start: 0, end: -6) => Blue background
xAxis (start: 0, end: -4) and yAxis (start: 0, end: 6) => Red background
xAxis (start: 0, end: -4) and yAxis (start: 0, end: -6) => Orange background
I'm at a slight loss on how to do this natively by extending echarts.apache so any help would be appreciated for custom chart examples or an idea of how to execute this.
I can only get the background of the full chart example

QUESTION
I got an issue with showing hover tooltips with ECharts line graph when all input values of the graph are null.
The use case is a graph that might have some null/undefined values at certain points in time. For normal values, the graph would show the tooltip as usual. Whenever the value of the graph is null or undefined, I want the graph still show the hover tooltip but with custom format, for instance, 'N/A'.
The example code snippet is a simple EChart configuration that I took from EChart line graph examples and change the input data to null.
