[tiller1010]

https://werkbotstudios.teamwork.com/app/tasks/39646343

Summary

• index debug mode
• check for updateIndexQuery in dataextensions

Testing Steps

• (optional) test with reed searchable files, confirm they can be published
  • (optional) extend the Image class with its own index query (using updateIndexQuery), confirm this works as expected
• mess up an index query, add ?debug to the search index task, confirm your query shows with the error

Git Flow

• DO NOT delete "release/*" or "hotfix/*" branches after merging a PR. These are used to publish the next release, and they are deleted automatically.
• "Squash and merge" is good on "feature/*" into "develop"
• "Create a merge commit" is good on "release/*" or "hotfix/*" into "main"

This looks good!

Could try and catch the exception - though I guess that depends if you want the index to continue and just notify the user or if you want it to stop immediately
