item.update() is breaking WAB apps

AngusHooper1

Morning,

I am trying to create a script that searches an items dependencies & data, finds legacy URL's/services and updates these to the new version of that URL/service.

Example of script

orig_data = item.getdata()

new_data = orig_data.replace(old_url, new_url)

item.update(item_properties=None, data=new_data, thumbnail=None, metadata=None)

The outcome of this script, when used with WAB Apps, is the app breaking and returning an error page of "'False' is undefined". What is wrong with the above methodology for WAB Apps? Is there an alternative workflow to achieve the same end goal of updating legacy dependencies that are baked into a WAB App?

Okay, if that is what you're trying to update the workflow you described isn't quite what I had in mind. What happens if instead you do:

app_data <SPAN class="operator token">=</SPAN> item<SPAN class="punctuation token">.</SPAN>getdata<SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN>
app_data<SPAN class="punctuation token">[</SPAN><SPAN class="string token">'geometryService'</SPAN><SPAN class="punctuation token">]</SPAN> <SPAN class="operator token">=</SPAN> <SPAN class="string token">'https://thisisanupdate.com'</SPAN>
item_properties <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">{</SPAN><SPAN class="string token">"text"</SPAN><SPAN class="punctuation token">:</SPAN> json<SPAN class="punctuation token">.</SPAN>dumps<SPAN class="punctuation token">(</SPAN>app_data<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">}</SPAN>
app<SPAN class="punctuation token">.</SPAN>update<SPAN class="punctuation token">(</SPAN>item_properties<SPAN class="operator token">=</SPAN>item_properties<SPAN class="punctuation token">)</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

This update is successful for me and the application continues to work.
