Explanation
According to the scenario, the DataCollector flow sometimes fails because some fields on web pages are missing or have different attributes than expected. To resolve this issue, you can use one of these two methods:
Add an If web page contains action before each Populate text field on a web page action to determine whether a field exists on the web page and write data only when true. This way, you can avoid errors caused by missing fields.
Modify selectors for each Populate text field on a web page action to ensure that field attributes are mapped correctly and match those on web pages. This way, you can avoid errors caused by mismatched attributes.
