error: failed to read input object (not a Template?): error converting YAML to JSON: yaml: mapping values are not allowed in this context

What does this error mean? Is it due to indentation? Is there any way to auto align yaml files

I tried fixing it by aligning etc but it didn't work and my jenkins build is failing.

- name: SPLUNK_LOG_TOKEN
   valueFrom:
    secretKeyRef:
        name: splunk-secret
        key: splunk.token
- name: SPLUNK_LOG_URL             //error in this line
   valueFrom:
    configMapKeyRef:
       name: splunk-config
       key: splunk.url

The following is invalid YAML (in both items):

- name: SPLUNK_LOG_TOKEN
   valueFrom:

This is because valueFrom is more indented than name. Thus YAML thinks that valueFrom is a continuation of the scalar SPLUNK_LOG_TOKEN. However, a : follows which ends an implicit mapping key. And implicit mapping keys are forbidden in a multi-line scalar context, hence the error.

Is there any way to auto align yaml files

Indentation in YAML is part of the semantic (like in Python). You are basically asking whether you can guess the intended semantic for badly indented files. While this is theoretically not impossible (I mean, you could train a neural network on YAML syntax questions on StackOverflow; I have seen this particular problem countless times), I don't think a readily usable solution exists.

The probable solution for your problem is

- name: SPLUNK_LOG_TOKEN
 valueFrom:

however, I can't be 100% sure; perhaps you rather want to do something like

- name:
    id: SPLUNK_LOG_TOKEN
    valueFrom:

if valueFrom should be a child of name.

The highlighted one is the invalid yaml pattern's. - name: SPLUNK_LOG_TOKEN - name: SPLUNK_LOG_URL.

It should be something like this

- name: 
   name: SPLUNK_LOG_TOKEN
   valueFrom:
    secretKeyRef:
        name: splunk-secret
        key: splunk.token
- name:             
   name: SPLUNK_LOG_URL 
   valueFrom:
    configMapKeyRef:
       name: splunk-config
       key: splunk.url

If you are JSON lover like me, then you can try this online converter https://www.json2yaml.com/convert-yaml-to-json

When I was new to yaml, I used to write smaller chunks of JSON data and get it converted using the online https://www.json2yaml.com/convert-yaml-to-json into YAML format. There are also other tools available online, but from personal experience I preferred this.
