im trying to make a request to spotify with spotify api BUT when im filling the weboptions parameters and then execute the webread this is the result:

error: weboptions: HeaderFields must be of size m-by-2

error: called from

set.HeaderFields at line 311 column 11

webread at line 89 column 24

my code is here:

options=weboptions('HeaderFields',{'Accept' 'application/json';'Content-Type' 'application/json';'Authorization' 'Bearer BQCS1-3qa1vbElaF9wa2hoZacWQfULK_aH5QJt5bqAAYQ0oBBPXxjtbTg5X--DkI8cNdwdQ5dyP5ohpTDYAPMIkBmytfptLBUvRl4ZM14BIhO0By2DxcQvurUcaGjHSgEjfBOLQO2W9ok5aw0HEjZQ-HZh1IFvLFSamM-gqVFIeYYRsXQXk'})

then i execute the webread:

response=webread("https://api.spotify.com/v1/me",options)

the auth-token is copied exactly from the spotify website where i created the token

The code you posted had

options=weboptions('HeaderFields',{'Accept' 'application/json';'Content-Type' 'application/json';'Authorization' 'Bearer BQCS1-3qa1vbElaF9wa2hoZacWQfULK_aH5QJt5bqAAYQ0oBBPXxjtbTg5X--

which was split across two lines and did not construct the strings properly. I removed the newline to join it together into one string

options=weboptions('HeaderFields',{'Accept' 'application/json';'Content-Type' 'application/json';'Authorization' 'Bearer BQCS1-3qa1vbElaF9wa2hoZacWQfULK_aH5QJt5bqAAYQ0oBBPXxjtbTg5X--DkI8cNdwdQ5dyP5ohpTDYAPMIkBmytfptLBUvRl4ZM14BIhO0By2DxcQvurUcaGjHSgEjfBOLQO2W9ok5aw0HEjZQ-HZh1IFvLFSamM-gqVFIeYYRsXQXk'})

under the assumption that the split was an artificat that did not exist in your actual code. The resulting line worked fine for me.
