bigquery does not load JSON - google-bigquery

Question

I have this JSON:
{'category':'runtime_exception',
'action':"Cannot read property 'isCurrentlySorted' of undefined",
'value':'TypeError: Cannot read property "isCurrentlySorted" of undefined at Ht.SetSectionCurrentlySorted',
'current_url':'/drugs-list',
'serial_number':'A4001-2816',
'session_id':null,
'timeStamp':'2021-08-10T14:11:10.309Z',
'localTimeStamp':'Tue Aug 10 2021 17:11:10 GMT+0300 (Israel Daylight Time)',
'user':{'machine':null,'info':{'user_id':'yuval.haliva#eitanmedical.com'}},
'event_id':9}
When uploading it to bigquery, I get this error:
Error while reading data, error message: JSON parsing error in row starting at position 0: No such field: category.

Your JSON is invalid. Here is a quick overview for basic JSON syntax: https://www.w3schools.com/js/js_json_syntax.asp
In short, use double quotes (") to encapsulate your keys and values instead of single quotes ('). There are a lot of online JSON validators out there. Here is an example: https://jsonformatter.curiousconcept.com/
It auto-corrects your JSON to:
{
"category":"runtime_exception",
"action":"Cannot read property 'isCurrentlySorted' of undefined",
"value":"TypeError: Cannot read property \"isCurrentlySorted\" of undefined at Ht.SetSectionCurrentlySorted",
"current_url":"/drugs-list",
"serial_number":"A4001-2816",
"session_id":null,
"timeStamp":"2021-08-10T14:11:10.309Z",
"localTimeStamp":"Tue Aug 10 2021 17:11:10 GMT+0300 (Israel Daylight Time)",
"user":{
"machine":null,
"info":{
"user_id":"yuval.haliva#eitanmedical.com"
}
},
"event_id":9
}
