[bug] Malformed marker payload when marker name is a number

Tell us about your environment

• Browser and Browser Version: Chrome 100.0.4896.127 on Windows 11
• After Effects Version: Don’t know. Can investigate if needed.

What did you do? Please explain the steps you took before you encountered the problem.

1. Obtain a JSON animation file containing some composition markers, each with a duration, which are named as numbers: 1, 2, 3
2. Integrate lottie-web in vanilla JS page and programmatically load animation into animatedItem. Autoplay is false, loop is false.
3. Upon some user event, programmatically play a specific marker segment through animatedItem.goToAndPlay('1'). At this point, also set loop to true

What did you expect to happen? Requested marker segment should play in loop

What actually happened? Please include as much relevant detail as possible. The whole animation plays in loop.

Please provide a download link to the After Effects file that demonstrates the problem. https://gist.github.com/BrainCrumbz/ce3b2cda9133c3f97d27e79ec2641391#file-marker_20220426_001_numbers_only-json

In case it might help, we’ll share here below some details of our investigation.

Hey thanks for the detailed info. I’ve been looking into it and this indeed fixes markers configuration. I think that it can also be solved by checking isNaN(_markers[i].cm)
If it is false, set the payload manually.
But the goToAndPlay and goToAndStop methods need an update as well since they are assuming that anything that can be cast as a Number is a frame and not a marker.
I can work on fixing it, but let me know if you want to address both issues together.

What marker name values do you think should be used as test cases? Will try to list some here:

"cm":"123",

"cm":"abc",

"cm":"abc\r\n",

"cm":"name: abc\r\ndescription: def",

"cm":"name: 123\r\ndescription: def",

"cm":"{\r\n  \"name\":\"abc\",\r\n  \"description\": \"def\"\r\n}",

"cm":"{\r\n  \"name\":\"123\",\r\n  \"description\": \"def\"\r\n}",

Are there more?
