Inject Javascript into selenium Python -> converted_args})['value']

I am trying to inject some javascript code into my chrome selenium browser. The javascript contains a token that is only valid one time and therefore the javascript can only be executed once. To inject the javascript I have used:

driver.execute_script(toinject)

Where toinject contains this javascript:

javascript:(function(){ var f = document.createElement("form"); f.setAttribute("id","destroyer"); f.setAttribute("method","post"); f.setAttribute("action","http://www.adidas.ch/on/demandware.store/Sites-adidas-CH-Site/default/Cart-MiniAddProduct?clientId=c1f3632f-6d3a-43f4-9987-9de920731dcb"); var masterPid = document.createElement("input"); masterPid.setAttribute("type","hidden"); masterPid.setAttribute("name","masterPid"); masterPid.setAttribute("value","BY9913"); var pid = document.createElement("input"); pid.setAttribute("type","hidden"); pid.setAttribute("name","pid"); pid.setAttribute("value","BY9913_620"); var ajaxOption = document.createElement("input"); ajaxOption.setAttribute("type","hidden"); ajaxOption.setAttribute("name","ajax"); ajaxOption.setAttribute("value","true"); var responseOption = document.createElement("input"); responseOption.setAttribute("type","hidden"); responseOption.setAttribute("name","layer"); responseOption.setAttribute("value","Add To Bag overlay"); var quantity = document.createElement("input"); quantity.setAttribute("type","hidden"); quantity.setAttribute("name","Quantity"); quantity.setAttribute("value","1"); var sessionSelectedStoreID = document.createElement("input"); sessionSelectedStoreID.setAttribute("type","hidden"); sessionSelectedStoreID.setAttribute("name","sessionSelectedStoreID"); sessionSelectedStoreID.setAttribute("value","null"); var captchaToken = document.createElement("input"); captchaToken.setAttribute("type","hidden"); captchaToken.setAttribute("name","g-recaptcha-response"); captchaToken.setAttribute("value","03AMPJSYXHk0axYBy3sJEKk7pSbaubS9c0Du3y87zzid05zpMpMvyzWdqRQmbPqVM2cxd9j3RNjMyX7x3_NOmo7NhlJD0YjyZlwG13AIGwHZ9E0IYqX1YyxAO162pXPxZboq4M47CA9Sf2BDdwIPjHsPgOX3ELuFeWR38Su0jsrrJoQ1ti49wllmsM3EbfSM4PXoudbary0NmXrSC2qpkQ0H3SkIbW3cfiwnDPm6s5bWlznjFAwtuDBbWGm7FC2TizgPr_nVRW4hh7E9F_lEkTWS-BIQFsan2huh7z-eK1Q1WEYUC9ReDg87GoKPF0CAz3yfanh_hbfHr7yMVSxqkQznGXmNQ-tj8gfa9PVwKM5BUT_-ofQliUBgEWePQN31cStqRxDuUesGyB"); f.appendChild(captchaToken); var captchaDuplicate = document.createElement("input"); captchaDuplicate.setAttribute("type","hidden"); captchaDuplicate.setAttribute("name","x-PrdRt"); captchaDuplicate.setAttribute("value","03AMPJSYXHk0axYBy3sJEKk7pSbaubS9c0Du3y87zzid05zpMpMvyzWdqRQmbPqVM2cxd9j3RNjMyX7x3_NOmo7NhlJD0YjyZlwG13AIGwHZ9E0IYqX1YyxAO162pXPxZboq4M47CA9Sf2BDdwIPjHsPgOX3ELuFeWR38Su0jsrrJoQ1ti49wllmsM3EbfSM4PXoudbary0NmXrSC2qpkQ0H3SkIbW3cfiwnDPm6s5bWlznjFAwtuDBbWGm7FC2TizgPr_nVRW4hh7E9F_lEkTWS-BIQFsan2huh7z-eK1Q1WEYUC9ReDg87GoKPF0CAz3yfanh_hbfHr7yMVSxqkQznGXmNQ-tj8gfa9PVwKM5BUT_-ofQliUBgEWePQN31cStqRxDuUesGyB"); f.appendChild(captchaDuplicate); var s = document.createElement("input"); s.setAttribute("type","submit"); s.setAttribute("value","Submit"); f.appendChild(masterPid); f.appendChild(pid); f.appendChild(ajaxOption); f.appendChild(responseOption); f.appendChild(quantity); f.appendChild(sessionSelectedStoreID); f.appendChild(s); document.getElementsByTagName("body")[0].appendChild(f); })(); document.getElementById(document.querySelector("[id^='destroyer']").id).submit();

It is very long but im pretty certain it is correct because it works if I run it using a javascript tester. What happens after is, the javascript seems to be executed twice, making the token invalid. I get the following error:

How can I avoid this? I have'nt found anyone with the same problem for the past 3 hours. I don't mind injecting the javascript another way but I don't know any. Thank you in advance
