Dashboard not loading with error, "totalQuery is undefined"

[sylim_splunk]

Some of my dashboards are not loading after the 7.3.x upgrade - which were all Okay with the previous version was 7.2.6.
The error messages are different from browsers but common thing is, the dashboards are not loading with the errors.
Errors are, as below with invalid line numbers.

totalQuery is undefined or

undefined is not an object (evaluating 'totalQuery.replace')

This is caused by some post-process searches, such as if a post-process search doesn't contain <query> element, then dashboard is not loading. This is due to JavaScript undefined error. And can be worked around by adding empty query element for the post-process searches without query. This is just a temp workaround and may not be needed once fixed (7.3.4+, 8.0.1+).

for example, below is Okay
<search base="callsA" id="myTable">
<query>
| search call_id="$token1$"
...<SNIP>
</query>
</search>

But if a post-process search doesn't have any query but only has some options, which will cause the error/symptoms (SPL-178012).
<search base="callB" id="yourTable"></search>

It can be worked around by adding empty query element as below.

<search base="callB" id="yourTable">
<query></query>
</search>
