PHP Fatal Error When Connecting Account

Hi, I hope you’re well.

Today I’ve tried connecting PayPal account by clicking ‘Click to Connect’ button. This resulted in a PHP fatal error. This is what I could see in the browser console:

“Failed to load resource: the server responded with a status of 500 (Internal Server Error) – /wp-admin/admin-ajax.php?action=wc_ppcp_admin_request[…]“

“Uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘code’)
at P. (api-settings.js:127:20)
at l (regenerator-runtime.min.js?ver=0.14.0:1:1768)
at o.value (regenerator-runtime.min.js?ver=0.14.0:1:1581)
at Generator.next (regenerator-runtime.min.js?ver=0.14.0:1:2195)
at r (asyncToGenerator.js:3:20)
at c (asyncToGenerator.js:25:9)”

And this PHP error from the error log:

PHP Fatal error:  Uncaught TypeError: Cannot access offset of type string on string in wp-content/plugins/pymntpl-paypal-woocommerce/src/Rest/Routes/Admin/ConnectAccount.php:52\nStack trace:\n#0 /wp-content/plugins/pymntpl-paypal-woocommerce/src/Rest/Routes/AbstractRoute.php(28): PaymentPlugins\\WooCommerce\\PPCP\\Rest\\Routes\\Admin\\ConnectAccount->handle_put_request(Object(WP_REST_Request))\n#1 /wp-includes/rest-api/class-wp-rest-server.php(1230): PaymentPlugins\\WooCommerce\\PPCP\\Rest\\Routes\\AbstractRoute->handle_request(Object(WP_REST_Request))\n#2 /wp-includes/rest-api/class-wp-rest-server.php(1063): WP_REST_Server->respond_to_request(Object(WP_REST_Request), ‘/wc-ppcp/v1/adm…’, Array, NULL)\n#3 /wp-includes/rest-api/class-wp-rest-server.php(439): WP_REST_Server->dispatch(Object(WP_REST_Request))\n#4 /wp-includes/rest-api.php(428): WP_REST_Server->serve_request(‘/wc-ppcp/v1/adm…’)\n#5 /wp-content/plugins/pymntpl-paypal-woocommerce/src/RestApi.php(28): rest_api_loaded()\n#6 /wp-includes/class-wp-hook.php(324): PaymentPlugins\\WooCommerce\\PPCP\\RestApi->process_admin_request(”)\n#7 /wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(”, Array)\n#8 /wp-includes/plugin.php(517): WP_Hook->do_action(Array)\n#9 /wp-admin/admin-ajax.php(192): do_action(‘wp_ajax_wc_ppcp…’)\n#10 {main}\n  thrown in /wp-content/plugins/pymntpl-paypal-woocommerce/src/Rest/Routes/Admin/ConnectAccount.php on line 52, referer: /wp-admin/admin.php?page=wc-settings&tab=checkout&section=ppcp_api

Could you support me with this problem, please?
