We catch SDODS errors in a small wrapper to add our own reporting. The self-healing guide's resolution diagram ends at a node labelled SdodsHealError, so I wrote:
if (err.constructor.name === 'SdodsHealError') { /* ... */ }which never fires. What we actually get is a SdodsError. Which one is right?
Accepted answer
The output is right and the diagram is wrong. There is no SdodsHealError. The healer throws SdodsError with the code HEAL_FAILED, a message naming the description and the primary selector, and a hint listing the probe scores.
Match on the code, never the class name:
if (err instanceof SdodsError && err.code === 'HEAL_FAILED') { /* ... */ }Every structured error carries code, message, hint and docsUrl, and with --json they are printed as JSON on stderr, so the code is the stable thing to key on in either shape. I will get the diagram label fixed.
Have the same question?
Ask it with the command you ran and the output you got, and it will be answered here.
