Although the original post had other issues (i.e. the missing "-d"), the error message is more generic.

curl: (3) [globbing] nested braces not supported at pos X

This is because curly braces {} and square brackets [] are special globbing characters in curl. To turn this globbing off, use the "-g" option.

As an example, the following Solr facet query will fail without the "-g" to turn off curl globbing: curl -g 'http://localhost:8983/solr/query?json.facet={x:{terms:"myfield"}}'

It should be mentioned that the Accept header tells the server something about what we are accepting back  whereas the relevant header in this context is Content-Type  It s often advisable to specify Content-Type as application json when sending JSON  For curl the syntax is   -H  Content-Type  application json    So the complete curl command will be   curl -H  Content-Type  application json  -H  Accept  application json  -X PUT -d    tags    tag1   tag2    question   Which band    answers     id   a0   answer   Answer1     id   a1   answer   answer2      http   example com service

Try using a single quote instead of double quotes along with -g    Following scenario worked for me  curl -g -d    collection     NumberOfParcels  1  Weight  1  Length  1  Width  1  Height  1     -H  Accept  application json  -H  Content-Type  application json  --user test testmail com 123456 -X POST  https   yoururl com   WITH   curl -g -d    collection     NumberOfParcels  1  Weight  1  Length  1  Width  1  Height  1     -H  Accept  application json  -H  Content-Type  application json  --user test testmail com 123456 -X POST  https   yoururl com   This especially resolved my error curl command error   bad url colon is first character

Your command line should have a -d --data inserted before the string you want to send in the PUT  and you want to set the Content-Type and not Accept  curl -H  Content-Type  application json  -X PUT -d   JSON          http   example com service  Using the exact JSON data from the question  the full command line would become  curl -H  Content-Type  application json  -X PUT       -d    quot tags quot    quot tag1 quot   quot tag2 quot              quot question quot   quot Which band  quot             quot answers quot     quot id quot   quot a0 quot   quot answer quot   quot Answer1 quot                          quot id quot   quot a1 quot   quot answer quot   quot answer2 quot            http   example com service  Note  JSON data wrapped only for readability  not valid for curl request
