Install button on custom app is unable to click ( disabled/ grayed out

Topic summary

Install button for a custom Shopify app was disabled during the OAuth install flow on a developer store.

Observed symptoms:

  • Button grayed out; installation could not proceed.
  • Browser console showed “Minified React error #418” and 404 (resource not found) errors.

Initial hypotheses:

  • Issue might be on the app’s side; contact the app’s support.
  • App configuration may be incorrect (e.g., store whitelisting), so verify the app’s settings and target store.

Resolution and key action:

  • In the app management dashboard, set the app’s distribution to “install to specific store.”
  • After selecting this distribution option, the Install button became clickable and the flow proceeded.

Context:

  • OAuth (authorization) flow requires correct app distribution/permissions to enable installation.
  • “Whitelist store” means the app must permit installation on the intended store.

Outcome:

  • Issue resolved by correcting the app’s distribution configuration.
  • Console errors were observed but the decisive fix was adjusting the app’s distribution setting. Discussion closed.
