Webform Error - Expected one PriceSet but found 25

Question

I am using Webform with CiviCRM to enable a family to renew their memberships. On many of the submissions when I click View Contribution I get the following error:

CiviCRM_API3_Exception: "Expected one PriceSet but found 25"

#0 /var/www/html/sites/all/modules/civicrm/CRM/Contribute/Form/ContributionView.php(158): civicrm_api3("PriceSet", "getsingle", (Array:2))

Sorry but we are not able to provide this at the moment.
Expected one PriceSet but found 25

Return to home page.

It does not happen on all submissions and I have not been able to diagnose the cause. Has anyone else experienced this issue?

Answer 1

Webform doesn't use pricesets. Are you using a normal fully-configured contribution page that has a priceset? If so, try a simple contribution page as described here: https://wiki.civicrm.org/confluence/display/CRMDOC/Webform+CiviCRM+Integration#WebformCiviCRMIntegration-Acceptingpaymentsthroughawebform

Answer 2

I do not know what your set up is but the error is from an API call (entity PriceSet action getsingle) and it means it expects to find only one price set but it gets many. Can you check in your set up of the contribution page if you are using a price set and if it is set up properly?
